This page gives an overview to the options offered in Azureus/Vuze (current version when writing: 18.104.22.168).
Please note that the exact outlook of options in your Vuze depends on three things:
- Your User proficiency in Mode options. (See below)
- Your operating system. Some of the options are specifc only to certain OS (Windows, Mac, Linux, etc.)
- Selected Vuze interface. Some options are related to Vuze interface (az3), while some concern only the old Azureus interface (az2).
 Mode options
This allows you to alter the complexity of the controls that are offered to you. You might choose to set this to avoid the possibility of messing up the settings.
Beginner just allows managing of torrents, intermediate allows local trackers and many settings, advanced allows access to everything.
- Beginner is the default level for new users, and it hides some options and menu commands, which the users might inadvertently misuse. It also hides many available fields in column setup dialogs.
- Intermediate is the recommended level for most users who have managed to find this wiki.
- Advanced offers all the options for your tinkering, if you understand their function.
| The visibility of some options depends on your "User proficiency":
Since version 22.214.171.124, the Mode options page also contains a button to reset Vuze's main settings to default values. This button can be used for reverting back to defaults, if you think that your vuze settings have got too messed up.
 Startup options
Options for the actions you can set Vuze to do at startup/shutdown. The availability (and working) of the various options depends on your operating system.
 Connection options
- Incoming TCP/UDP listen port This is index number of the port to 'open' in your firewall or 'forward' in your router, if you go through any to the Internet. Azureus only uses one port for all torrents.
- From a Tracker
- Decentralized Tracking
- Supplied by another peer
- Added by a plugin
- Incoming connection (If you disable this, your Vuze will not accept remote connections)
- PublicIP Network
- I2P Network see http://www.i2p.net or Wikipedia
- The Onion Router (Tor) see http://tor.eff.org or Wikipedia
 Proxy Options
For use if you are behind a firewall.
Please note that these Proxy options are visible only if you have set user proficiency to "Advanced".
- Enable proxying of tracker communications The following options are for use if you're using a proxy to connect to the internet.
- I have a SOCKS proxy check this if you're using a SOCKS proxy.
- Enable proxying of peer communications enables you to use a proxy when uploading information to the peers (seeding and all uploads).
- Inform Tracker of limitation check this to let the tracker know you're using a proxy.
- SOCKS version The version of the SOCKS protocol your proxy uses.
- Use same proxy setting for tracker and peer communications proxy Check this to use the same settings for the peer and the tracker proxy.
 Advanced Network Settings
- Max simultaneous outbound connections attemptsThis options set limits how many connection attempts can be "half-open" simultaneously.
- Bind to local IP This option allows you to bind Azureus to a specfic IP address and thus a (virtual) network device. This may be useful if you have multiple internet connections. It can be used with the multi-instance flag and the LAN peer finder plugin to run multiple Azureus instances to use more than one line for downloading. This section needs more details and examples. How to use this with a VPN service should be detailed here.
- Bind to local Port This sets outgoing connections to a fixed source port. This can be used with full cone NAT routers to reduce the number of NAT table entries and thus prevent crashes on some router models. When the outgoing port is bound to the same as the incoming port that might even solve NAT problems on full cone NAT routers.
- Note: Binding to the same port as the incoming port works under Windows 2k and greater only. Unix users should use a different port. It's not working at all under Mac OS X.
- Line maximum transmission Unit The greatest amount of data or "packet" size that can be transferred in one physical frame on a network.
- Socket SO_SNDBUF size The TCP window size is implemented by send and receive buffers on each end of the connection. To set these buffers, the SO_SNDBUF and SO_RCVBUF fields need so be changed (KB).
- Socket SO_RCVBUF size see Socket SO_SNDBUF size
- Outgoing packet type-of-service Sets traffic class / type-of-service (TOS) field in the IP header for outgoing packets.
- Azureus leaves this unset by default, meaning the defaults for the underlying OS are used.
- Example values are:
- 0x02 for IPTOS_LOWCOST
- 0x04 for IPTOS_RELIABILITY
- 0x08 for IPTOS_THROUGHPUT
- 0x10 for IPTOS_LOWDELAY
- Underlying network implementations may ignore this value, so this option is highly dependent on OS and JRE versions.
- On Windows 95/98/NT for TCP sockets the IP_TOS socket option is ignored and all packets are sent with the TOS set to 0.
- On Mac OS X setting TOS does not work yet, due to a bug in Apple's JRE.
- On Windows 2000 and XP IP TOS needs to be enabled via the registry setting HKEY\LOCAL MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters\DisableUserTOSSetting as a REG DWORD type set to the value 0.
- Note:Azureus 126.96.36.199 and newer will automatically set this registry key for you when enabled (reboot required).
 Transport Encryption
- Require encrypted transport
- Minimum encryption level
- Allow non-encrypted outgoing connections...
- Allow non-encrypted incoming connections
Some SOCKS proxy servers suffer from relatively high service disruption (proxy server instances being unavailable, name resolution failing) and this has lead to the introduction of the ability to use alternative DNS servers for resolving the available IPs (along with some work to make the proxy server selection more robust). Rather than place the configuration under the Proxy section it has been allocated its own area as in the future the use of alternative servers may well be extended beyond its use for SOCKS.
By default Google DNS has been added to the set of servers.
Pairing is a feature that makes it easier for remote interfaces and applications to link to Vuze.
Without pairing it is necessary to manually find the public IP address of Vuze in order to connect to it. Often ISPs will periodically change the IP address which means continually having to keep track of the current one assigned. Also, each remote service will have a separate port assigned to it, so this has to be kept track of as well.
Pairing automates this process by keeping an up-to-date record of Vuze's public IP, along with the various remote services installed. An access code is used to control access to this information, all that you need to remember is this code. It is of course still possible to control access to the individual services via username/password, the access code simply gives access to the current IP and service ports your Vuze has defined.
Currently remote services need to be directly connectable from the Internet - that is the relevant ports need to be open (either via UPnP or manually configured)
 Transfer options
Only experienced users should change these options. You can badly hurt your download speed. If you are new to Azureus, use Azureus > Tools > Configuration Wizard. You should also read Good settings.
These values are initially taken care of through the configuration wizard run the first time you start up Azureus on your system. They are very dependant on your internet connection and what capacity you want to make available to BT activity. If you want to vary some of these parameters to better settings then the configuration wizard is available through the File Menu. Only experienced users should change these options because you can badly hurt your download speed.
| Note: Options' visibility depends on your "User proficiency" set in Mode options:
- Global max upload speed and Global max download speed set the maximum amount of the network capacity that you will allow BT activity to use for up-/download. Upload should be about 80% of the bandwidth on your internet connection
- Alternate rate when only seeding defines the max upload speed if there are only uploading torrents.
- Speed bias for downloading torrents: thee options define if you want to bias the distribution of your upload speed in favour of downloading torrents in order to speed downloads thanks to increased uploads (tit-for-tat).
- Max upload slots per torrent default is the number of people to whom you will upload data on a torrent. This value balances potential speed increases with fewer peers against more peers at possibly lower speeds. This can be altered for individual torrents in the 'General' tab for that torrent. Allow at least 2 kB/s for every upload slot for best performance.
- Alternate default when seeding defines the default value if there are only uploading torrents.
- Max number of connections per torrent default is the maximum number of peers to which you can be connected on a torrent per default. Sets the default number of seed and peer connections each torrent can have. A higher-than-optimal number here is the primary cause in reports of computer lagging when Azureus runs. Usually, 30 to 60 connections per torrent will suffice. Set it to 100 or 150 and your transfers may slow as protocol overhead increases noticeably.
- Max connections globally is the total number of peers, for all torrents, to whom you will allow connections from this client.
- Prioritize most completed files where your client resources are limited Azureus will make more attempts to complete file downloads, and therefore usable, instead of maximising transfer rates.
- Allow multiple connections from the same IP leave this disabled unless you have a specific need for it or enjoy people leeching your bandwidth.
- Use lazy bitfield sends altered bitfield information when torrents switch from downloading to seeding. At least Optonline detects the normal bitfield and sends spoofed packets to both peers causing the clients to terminate the connection. You should only use this option if you need to.
- Prioritize first and last piece of file(s) tries to download the first and last pieces of individual files in the torrent. This allows previewing certain media files before they are completed. Those files are usually large, so this is of little use. VLC Media Player is a better alternative.
- Further prioritize High priority files according to % complete and size of file ???
- Ignore peers with these data ports ignores peers who have set these port numbers for their incoming connections. If your firewall complains that Azureus is trying to send email, then your firewall may be brain-dead and you should add 25 here.
Here you set Vuze to automatically adjust its speed limits either with Auto-Speed Classic or with Beta version. You can set the functionality to be active when downloading and seeding, or when only seeding.
The main parameters for Auto-Speed Classic:
- The min/max limits for uploads
- Max increase/decrease to the speed
- The choking ping time (latency in ms). Lower time here means more sensitiveness for smooth internet traffic.
The main parameters for Auto-Speed Beta:
Separate speeds for LAN connections enable you to set different max. speeds for those peers, which are located in the same LAN with you. For most users, there is no other peer in the same LAN and this "LAN speed" setting should be disabled.
 Files options
This set of preferences allows you to fine tune the way Azureus handles the files it creates.
- Default directory defines a directory path you would like your torrents to automatically download into. This is one of the most useful settings here, as it enables you to relocate your data directory for new downloads. If you have activated this option, it's still possible to download a torrent to a different directory by using the File -> Open menu.
- Allocate and zero tells Azureus to pre-allocate the space to be used by the file and fill that space with zeroes before it starts downloading the actual data of the file. This means that there is no chance that later Azureus will stall because there is not enough space on the destination disk. As the file is created at once, this option will also minimize fragmentation of the hard drive in comparison to incremental allocation. (If this option is checked, incremental file creation can not be used.)
- Note: Default for this option is 'disabled', but enabling this option might be beneficial for most users, as the whole files to be downloaded would be created when torrent is added to Azureus.
- Enable incremental file creation will make Azureus increase the size of the file only as it is data is downloaded which means that you can trigger torrents that may take up a lot of space and that space will in reality remain available until actually needed to store file content. (If this option is checked, pre-allocation can not be used.)
- Note: Selecting this option will result in Azureus only reserving as much disk space as is necessary for writing the last piece it has received. For example, if it first received piece 125 of a 1000 piece torrent, it would reserve space for pieces 0-125 in the torrent. If then it next received piece 500, the reserved space would increase to half the complete size of the torrent as pieces 126-500 would be alloacated. So, although only two pieces (0.2%) of the torrent are downloaded, 50% of the disk space is still already taken. Because you may have several torrents doing this at once, as well as other processes writing to the disk, this method will result in more fragmentation than using pre-allocation. It may also cause unnecessary peaks to hard disk usage. Additionally, as pieces are downloaded in random order and priority based on piece rarity, this option is very seldomly useful.
- Append data to files as downloaded... option enables Vuze to write downloaded pieces in mixed order and then arrange the file to proper order after the download completes. Note: new functionality in version 4.5, use with own risk.
- Truncate existing files will remove additional bytes at the end of a downloaded file (e.g. that has been imported from an other BT download tool). The option is most useful with MP3 files, to which some media players and inxeders (like Windows Media Player, Roxio, etc.) will automatically add tag information fetched from internet. See also info about Existing data file length too large error message.
- Re-check pieces when download is done instruct Azureus to do a check at the end of download to be completely sure no piece of a file was missed. If any piece doesn't pass the error correction, it is simply discarded and downloaded again. This option may cause occasional high CPU usage on slow systems.
- Enforce exclusive file write access locking across torrents This option was setup to deal up with issues involving multiple torrent. If you are getting errors that prevent download try removing this check. This page explains more: Multiple_torrents_accessing_shared_file(s)
- Use Fast Resume mode saves the state of your downloads into the .torrent file so that if you stop and restart a torrent it will resume 'instantly'. If you don't do this then Azureus will conduct a review of the download on startup to check the torrent content, which can take time. You can specify the interval between saves which will then be the maximum time you would loose if you had to restart. You can also instruct Azureus to save the information about peers to speed up restarts.
- Update resume data every X minutes defines how frequently resume data is written to the .torrent file.
- On crash-restart check entire file for completed pieces... forces Azureus it detects that in case Azureus detects that the session did not end gracefully, to make sure that the file contents are correct. From error correction perspective this is good, but it may also cause quite heavy disk activity when starting the session. Read also Vuze did not shutdown tidily.
- Save peer connections for quick reconnects caches information about the peers it's connected to and stores it in the .torrent file. This cached information makes it possible to connect to peers and seeders even in the case of the tracker going offline.
- Max peers to save sets the maximum number of peer connections to cache (per torrent).
- Auto-prioritize files with extension... lists extensions of files inside torrents that will automatically be given a download priority of High. Individual file priorities can be viewed on the files tab of the advanced view.
- Confirm when deleting data request a confirmation before deleting downloaded data. Deleted data does not go to the recycle bin.
- Files to ignore when creating/deleting... defines the files ignored when creating/deleting data files. Typically the low-level information files of the operating system.
- Move deleted files to the Recycle Bin prevents the files being deleted completely for recovery purposes. If the operating system supports an Recycle bin / trashcan, it will be used.
- Backup configuration files for recovery purposes tell Azureus to keep backup copies of the configuration files. At each Azureus session, the old configuration files are copied as .bak files (e.g. 'azureus.config' to 'azureus.config.bak') in the Configuration directory.
- With certain operating systems (Mac OSX, Linux ?) you may also see here options related to the XFS file system. If you get error messages that XFS file allocation failed, you may try to turn off the XFS option Allocate new files using a method specific to XFS filesystem.
- Beta versions since 188.8.131.52_B05 contain an additional File deletion option related to the action for the 'Delete' button on the top toolbar: Does the button ask, or just remove torrent (and delete data file). The deletion options have also been grouped better:
 Completion Moving
- Move completed files will move the files from the download directory to another location when they are completed.
- Directory is the directory you want torrents to be moved to when they finish downloading and start seeding. Unchecking this option will result in torrents staying in the download directory. It can be hard to tell the difference between finished and incomplete torrents however, so it's recommended they be separated
- Move .torrent will also move the .torrent file from its saved location (see below) to the completed files directory. Can be useful to keep track of .torrent files for later reseeding.
- only if in default data directory will only move torrent to the completed directory if it was originally saved to the default data directory. This is useful if you have certain torrents you want saved somewhere else, otherwise when they finished downloading they'd just get moved into the completed directory with the others.
- Save .torrent files. Whenever Azureus opens a torrent, it will place a copy of the .torrent file in the selected directory.
- Save directory. Enter the directory you want to save your .torrent files in.
- Save backup. You may want to save a backup of your .torrent files in case something happens to the original. Checking this option will make Azureus place a copy of the .torrent with the extension .bak in your .torrent save directory.
- By default add new torrents in a stopped state. If you want new torrents to be in "stopped" state rather than the normal "queued".
- Import new .torrents automatically lets you choose a directory that will be periodically scanned for new torrents and automatically added to Azureus’ queue.
- Import Directory. Sets the directory to be monitored.
- Interval. Sets how often to scan the directory for new .torrent files.
- Begin stopped. Will load the torrent in a stopped state rather than queuing it.
 Decoding Character Sets
These options control Vuze's reaction to strange character in file names (of files included in a torrent). You can instruct Vuze to convert foreign characters to local characters and you can define the default character set to be used.
 Removal Rules
These options control how and when torrents are automatically removed from Vuze.
- By default, Vuze will only remove updates (for Vuze components) when they are no longer needed.
- Some trackers can issue an error response such as "torrent is not authorized by this tracker". You may configure Vuze to automatically drop the torrent when such error messages are received.
- This type of error message from a tracker can be generated if the torrent was never authorized by the tracker, or when the tracker administrator wishes to prevent further distribution of bittorrent content for a particular torrent. The latter case is common among trackers which distribute fansubbed anime, which eventually gets licensed - at which time distribution should cease. By enabling these features, you can help to prevent further distribution of bittorrent content that is no longer authorized for distribution.
These rules control how Vuze removes torrents automatically, either due to errors or because torrents are Vuze updates.
 Performance Options
- Friendly hash checking by default, Azureus uses friendly hash checking. You can disable this in the configuration. Friendly hash checking does not lock up your system while it does the hash checking. For faster systems, this should not be a problem but with slower machines, it can lead your system to be unusable until all the hash checking is done.
- Enable disk cache enables disk cache, this could help reduce disk fragmentation.
- Size of cache in MB (default 4) Important: set it to 32 MB or less!
- Trace cache operations for diagnostic purposes
 Interface options
These preferences allow you to configure the interface that Azureus presents to you.
So you can select:
- Auto open details tab which will add a 'details' tab to the main display window for each torrent as it is added. This tab will be named after the Torrent.
- Auto open download bar opens a download bar whenever a torrent is added.
- Enable system tray places an icon in the system tray.
- Close minimizes to system tray won't close Azureus if the windows is closed via the top right close button but minimize it to the tray
- Minimise minimizes to system tray minimize will only show a tray icon, nothing more
- Show download stats on hover controls the availability of speed & activity stats, when mouse pointer is on top of the icon in system tray. (Note: this is new option in 4.3, and earlier the default behaviour was to always show the stats.)
- Allow Azureus to send ...
- Show confirmation dialog on exit
- Show confirmation dialog on torrent removal
- Clear remembered dialog decisions
- Drag and drop action for directories sets the action for Azureus to take in the event that a directory is 'dropped' onto the application. The actions can be to open the contained torrents, to share the directory, to share the directory's contents or to share the directory's contents and the contents of any contained directories.
- Reset explorer file associations sets the .Torrent file extension to refer back to Azureus by default. This may be needed if other BitTorrent clients modify the reference.
Settings here enable you to select the language used in Vuze user interface. English is the default choice, and not all parts of the user interface have been translated to each language.
Settings here enable you to adjust Vuze's behaviour when starting.
Settings here enable you to adjust the outlook by selecting the shown information, used units and also the update intervals.
Note: the option Force values to be shown as IEC... controls how kiloByte amounts is shown. If enabled, 1 kB = 1024 bytes, and e.g. 10 kB/s gets shown as 10.0. If disabled, that 10 kB/s would be shown as 10.2.
Note: The table layout related options got separated into "Tables" options in beta version 184.108.40.206. Previously they were in the Display options (still in release version 220.127.116.11).
Tables options inclue options e.g. for GUI update frequency.
- Show program icon... enables you to have icon associated to the torrent's main file shown in the Name column.
- Always show torrents with DND... controls if torrents with Do-Not-Download files are calculated completed after the selected files have been downloaded, or if those torrents should still be handled as incomplete, and be shown among the incomplete torrents.
- Always show header/filter bar controls the visibility of the category/filter bar. If disabled, then the row is only shown if you have active items there.
- Show Files in... enables you you have an expandable tree of torrent's files shown in Library/My torrents view. (Note: Functionality introduced in beta version 4405.)
- Draw grid lines and fill blank areas affects the fanciness of the tables. Enabling the option may also cause higher CPU load.
- Double-click in torrent views sets the action for double-clicking a torrent's name in Library views. You can select between playing the file, showing torrent details and showing the files in folder. (Note: as of version 4.4 the option is visible in Vuze/az3 interface only, but it has effect also on az2/classic interface. In beta 4407_B02 and later, the options correctly visible both in az2 and az3 interfaces).
 Color Scheme
Settings define how Vuze should alert you regarding certain items.
- Protect Azureus using a password prevents the use of Azureus unless the password is known. The password will be requested when starting, quitting, or restoring the client from the system tray.
 IP Filters options
This allows you to block connections to specified addresses. You might do this to avoid known organizations or nodes that are behaving in ways you may not find beneficial.
Note: The old Safepeer plugin is incompatible and obsolete with current Vuze versions. The built-in IP Filters functionality has replaced the need for the plug-in. Please read Safepeer_Migration.
The options available here:
- Enable switches on the filtering by Azureus of IP addresses. That means you can enter a range of IPs that you don’t want to have access to your computer (which will mean all other IPs will have access except the ones that you specify).
- ALLOW which enables you to enable only specific IP addresses all others with be blocked.
- Save blocked IP ... means you don't have to type the specific IP each time Vuze is started.
- Block peers that ... adds the address of any sources of bad data to the block list. Associated options enable fine-tuning of the blocking rules.
- Ban a block ... allows that once a few bad addresses are blocked in a small range then the range will also be blocked.
You can acquire standard blocklists. Otherwise you can add an IP address or ranges of addresses along with a description for that specific range.
 Plugins options
Plugins offer you additional ways to extend and modify Vuze's behaviour.
The main view displays the plugins that are installed and its sub choices allow access to the option panels of each installed plugin. This is where you get to configure and control the plugins that are loaded with your copy of Vuze.
Also the version information for each plugin is shown here.
 Statistics options
Tell Azureus to save statistical performance and activity information to a file.
- Enable activates periodic statistical data saves
- Statistics save directory indicates where to save the files
- Statistics file name indicates the name to use for the files
- XSL file name ??? Style sheet to insert for the formatting of output ???
- Save frequency sets the frequency of those saves
- Export peer details ??? indicate whether the data output to the file should include peer details which could enlarge the file size considerably ???

 Tracker options
These options control how Azureus communicates with trackers.
Controls the built-in tracker capability of the Azureus client.
This is where you set up the Azureus’ embedded tracker.
- First you need to have a "fixed"? external IP address. Click on the "Check Address"? button and everything will be explained.
- You can then choose the port on which the tracker will operate.
- The "Tracker client poll interval (secs)"? is the time your tracker will ask the peers connecting to it to wait before asking the tracker again.
- On the tracker URL, which will be something like http://yourExternalIPAddress:6969/, you can choose to publish details about the torrents you are hosting (or just publishing). And the access to that webpage can be protected via a password ("Enable password on tracker web"?).
- "Publish torrent file and peer details"? gives even more information, on the webpage, about who is downloading the torrent and how much is being transfered.

 Logging options
Instruct Vuze how to log its activity
If you want to keep track of the console output, enable logging to file.
Vuze can publish RSS feeds for various things to allow these to be read by other Vuze clients (for example). Currently this is supported for Subscriptions (applies to all subscriptions, configure via Subscription options), Categories (right-click on a category button to enable) and Devices (right-click on individual device entries in the side-bar to enable).
By default the RSS feeds are available via http://127.0.0.1:6905/ - there is a very simple HTML UI to navigate to the actual RSS feeds from here.
Note that for devices there is also an 'html' option that gives a way of browsing the RSS resources in a browser (typically this is used to give remote HTTP access to transcoded content on devices)
 Queue options
Control the most important aspects of the client's torrent queueing behaviour. You set the download order of torrents by yourself, but for the seeding torrents Vuze has a queue system, which tries to prioritize the seeding torrents according to the rules/instructions you give. By default it tries to run those seeding torrents which have "highest demand" for data. The following example picture shows, how Vuze has calculated a Seeding Rank for all completed torrents:
The priority order of torrents is: First priority seeding, download, seeding.
In the previous picture, the Max active torrents setting has been set to 5 and Max simultaneous downloads to 2. Thus 2 First priority seeding torrents, 2 downloading torrents and finally 1 normal seeding torrent are started.
- Please note that as the First priority status overrides the Seeding rank, the First priority torrents have been started despite their low Seeding rank.
- Some of the torrents also have an asterisk ' * ' in their Seeding rank column, which asterisk indicates that the torrent has been recently started and its Minimum seeding time is still going on, and thus the torrent will not be automatically stopped before that time has gone. Please see the Seeding options section below.
The main Queue options:
- Max simultaneous downloads sets the max. number of torrents that can be downloading at the same time. (Setting that lower than the Max active torrents leaves some slots for seeding torrents)
- Max active torrents is the most important option of these. It sets the upper limit, how many torrents (downloading and seeding) can run at the same time. Setting it too high will lead to too little bandwidth for each torrent, so it makes sense to set the number reasonable according to your internet connection's speed. Read Good_settings
- Min simultaneous downloads reserves some slots for downloads despite the priority settings. It is a way to guaranteee that you will not only have seeding first-priority torrents.
You can also set some limits how to handle really slow torrents and some other minor settings.
Downloading rules can be used to automatically determine the order of incomplete downloads.
Seeding rules are a set of rules that determine a torrent's Seeding Rank, a measure of how much it needs to be seeded. For the most part, the options are self-explanatory.
The options at the Seeding page are rarely used, and most users can leave them to default values.
- Minimum seeding time in seconds tells Vuze how long it should at least run a torrent, if it gets started. A longer time value here decreases the constant swapping of the seeding order. Each time the queued torrent gets started, this time starts to run again.
- Use Super Seeding mode is useful, if you are the single original uploader of a torrent. This mode tries to distribute the uploaded pieces as widely in the emerging swarm as possible, so that the original uploader does not get repeated requests for the same pieces from several peers. This is only useful if you are sole original uploader in a new torrent, (which you have created).
- Automatically reposition torrents based on Seeding Rank is the main switch for queue logic. Turning that off leaves the seeding torrent queue to manual mode, and you have to change order by youself.
 Auto Starting
These rules determine the seeding rank logic used for rank calculation. There are several options to select from, with Peers:Seed Ratio being the usual one.
Default values serve most users well.
 First Priority
Here you can set the criteria governing which torrents receive first priority. First priority overrides seeding rank, so a torrent with first priority will be seeded until first priority no longer applies.
The settings are rather self-explanatory.
As First priority torrents have higher priority than downloads, the settings set here reflect your judgment which factors make the torrent really important for seeding. Vuze forces at least 0.5 ratio as the minimum for Share ratio.
 See also
 Ignore Rules
These rules define your wishes to when Vuze should stop seeding torrents. The torrents which match "Ignore rules" will not be started automatically, and the torrents will stop when reaching a limit set here. Naturally you can't set the Share ratio limit below 1.0.
