Hello, I've been using Vuze for about 3 years now and it's always been great, I could download a 700 MB film in roughly an hour with 75 seeds and few peers. I have recently moved house, hence I have changed the modem from Sky to BT Hub, and I downloaded a 2 GB game from Steam in literally 3 minutes yesterday, I have done a speed test and it turns out that I can download 40 MB a second! Vuze program maintains a lightweight footprint, doesn’t slow your computer down, and quickly downloads torrents. The Vuze torrent downloader for Windows or Mac makes it easy for you to find torrents online, whether you are downloading torrents from a tracker site, from a friend via magnet links, or anywhere else on the web.
How to determine your upload speed[edit]
To configure Vuze for optimum performance, you need to know the upstream capacity of your Internet connection, which can be obtained from your Internet Service Provider (ISP). Advertisements may include numbers like '1024/256 Kbps'; this represents the maximum bandwidth available to you. It is the number of kilobits per second (kbit/s or Kbps) you can download/upload with your connection. You may have seen speed measured in kilobytes per second as commonly reported by browsers. There is a difference between the two measures. In all likelihood, you upload slower than you download.
You may visit http://www.dslreports.com/stest or http://www.adslguide.org.uk/tools/speedtest.asp for online speed tests. Stop ALL Internet activity on your machine (including torrents) for a few minutes before running a test. Repeat it twice to reduce number anomalies.
You can always set Config > Transfer > kB/s global max. upload speed to 0 -- meaning unlimited -- and observe. In any case, do not let Vuze (or any other program for that matter) take up the whole upload bandwidth. There needs to be room for overhead such as acknowledgement signals (ACKs) and resend requests. Downloads will suffer if these signals cannot be sent. Set your upload limit to about 80% of the maximum possible.
How do I setup Vuze to download faster?[edit]
First is to make sure that you have setup your ports in Vuze properly especially if you are behind a firewall or router. You'll need to add an exception for Azureus.exe (the main Azureus process) to your Software firewall (Windows)]. If you are using a Mac, check your firewall settings under (System Preferences > Network). And it is necessary to forward Azureus' TCP and UDP listening port (see Tools -> Options -> Connection) from your router to your PC, there are 2 ways to do that:
When your Router supports UPnP you may want to enable it in the router configuration and in Vuze (Tools > Option > Plugins > UPnP)If UPnP isn't supported or doesn't work correctly you have to do manual Port forwarding.
Downloading as fast as your connection allows requires good settings based on the upload speed of your Internet connection. First, fix your NAT problem if you never see and do not Force Start your torrents. Running another P2P program while Vuze is running will stall your downloads badly.
NOTE: Make sure to check out: Bad Routers and Bad ISP's
How do I setup Port forwarding on my router?[edit]
To be able to setup rules to forward Vuze listening ports (UDP and TCP) as external port to the IP of your computer and the same port on your computer, visit http://www.portforward.com/routers.htm for more info.
Note: first find out the brand and exact version of your router, then select the router from the Routers page, skip over the advertisement page and then select Vuze on the application, and then you should arrive at the settings page.
What do I do if I have Firewall software?[edit]
Just like the wide array of routers available to consumers, so too is the list of software firewalls, and each has different features and capabilities. Because of this huge variance, we will again attempt to approach this as broadly as possible. A software firewall can offer the same protection that a router can and it can mimic the symptoms of a NAT error. So why should you use both? A router can only protect you from incoming data on certain ports - a good software firewall can monitor outbound traffic too. Consider this an added layer of security.
Vuze Leap Mac
If you use a software firewall on their PC, the following information applies to everyone who hopes to fix their NAT error.
You should never have more than one software firewall installed and in use at any given time (analogy: two drivers wanting control of a steering wheel).
In order for Vuze to run correctly, access/permission must be allowed.

Vuze Torrent DownloadsHaving problems with UPnP?[edit]Why do I lose Internet connectivity after a while?[edit]
The problem is most likely related to your router. Click here for more information.
Why are most of my torrents queued and not downloading?[edit]
On Windows:
Go to Tools > Options > Queue > Max simultaneous downloads and Max active torrents.
On Mac OSX:
Vuze > Preferences > Queue > Max simultaneous downloads and Max active torrents.
These numbers determine how many torrents run simultaneously. Do NOT change them before reading Good settings! Otherwise, you may see your download speed DETERIORATE. Make sure you are downloading good torrents, too.
The Max simultaneous downloads is the maximum number of torrents downloading at any moment.
The Max active torrents is the maximum number of torrents you download or seed at the same time.
Note: If you are downloading torrents from a third-party site, it's possible that the tracker is overloaded with requests and the client does not receive a response back from the tracker in the required amount of time. From the Advanced screen, try going to the details page of the torrent and see if the trackers are online. Click the tracker URL, your browser should open up and should pull up a page. Also try downloading content from Vuze and see if you would experience the same issue.
Why is downloaded/total size not equal to completion percentage?[edit]
Terms
Total size - Size of the data to download.
Downloaded - Size of the data already downloaded.
Done - Percentage of the data verified and written to disk.
Difference
Vuze downloads piece by piece, and multiple pieces at a time, so at a given moment, more has been downloaded than has been verified, so you will always have a 'done' percentage less than the downloaded vs. total size percentage.
On slow downloads, you will most likely download pieces twice (if it's slow, you request it from multiple peers hoping to get it faster but you will get it more than once as well).
If Vuze happens to crash ( very rare ;) ) the data downloaded will be counted but all the unfinished pieces will have to be re-downloaded on restart and that will again amplify the difference between the two.
Example
8MB file made of two 4MB pieces. You have downloaded one piece completely and have 2MB out of the second piece.
You have downloaded and verified one 4MB piece, out of 8MB to download, so your 'done' percentage is 50%. But you have actually downloaded 6MB out of 8MB so you are 75% complete. But we don't include that in the 'done' count because we don't know if the piece will pass the validation.
What do I do if my network connection keeps dying?[edit]
Vuze (and BitTorrent clients in general) place a great deal of stress on the networking system - particularly network card drivers, and router/modem firmware - which can cause them (and/or the OS) to crash or lock up under load. I would suggest looking to see if there are newer drivers/firmware available for your hardware, or replace the buggy things completely.
However, there are a few things you can try to help alleviate the problem:
? Limit the Maximum number of connections per torrent in Vuze > Tools > Options > Transfer to 40 or less, as well as limit Maximum number of connections globally to 100 or less.
? Reduce the Max simultaneous outbound connection attempts rate to 1 or 2 in Vuze > Tools > Options > Connection.
Note: If you are running Zone Alarm (version 5 in particular), you might try disabling or uninstalling it and rebooting. Many users have reported problems with ZA breaking BitTorrent clients.
Additional note: As a general rule, a lot of home-routers can only handle a total number of 255 connections open at any one time. Thus, if you have many machines running on one network, your router will quite likely occasionally either lock up / crash or randomly dump connections it decides it can't handle (depending on how well the firmware is written). Your only solution really is the above: reduce the number of possible connections (unless you can afford to shell out on an expensive corporate router that is!)
If it's your router that is dying and not your network card have a look at the bad routers page.
Why am I seeing a yellow bar every time I click on the 'Play or Download' link in Vuze?[edit]
This normally happens when your are using other browsers in Windows OS (i.e. Safari, Opera or Firefox). There are some issues with the Opera and Safari 3 (Windows Public Beta) browsers not associating the Java Web Start when clicking on the download link.
Note: This normally happens when the Vuze client is not running.
Opera Browser
Here is a work around to teach Opera to hand off *.jnlp files it finds to Java Web Start, javaws.exe.:
Safari 3 (Windows Public BETA)
Download the latest version available. If it still does not work, we suggest using a different browser instead.
Note: This is just a work around, but in doing these steps and you still experience some problems, the best solution is to browse content from the Vuze client and not from your browser.
The Internet gets slow when Vuze is active[edit]
If web browsing or e-mail usage seems slow while Vuze is active, or Vuze's speed constantly fluctuates going up and down, you may try to correct that by limiting Vuze's speed.
In general, Vuze uses as much internet bandwidth that you let it have. It downloads and uploads as fast as possible. In practice, most users have asymmetric ADSL or cable modem connection (like 1024/256kbit or 10/1MBit), where the upload is the critical factor, as it is much smaller that download bandwidth from your ISP. If Vuze takes over all your upload bandwidth, then even the web browsing gets slow as even your outgoing requests for web pages get slowed down. It also slows down your Vuze downloads, as data arrival messages and requests for new data also get stuck in the outgoing packet queue.
In most cases, you should not limit the download speed. You may limit it somewhat to leave room for web browsing etc., but in general the upload bandwidth is the one you should pay attention to.
The easiest way to try to correct 'slow internet' is to go to Vuze's Transfer options and set the 'global max upload speed' to 5-10 kB/s less than your max. upload bandwidth. (And please understand, that ISPs use kilobits/megabits, while Vuze uses kiloBytes by default. 1 Byte = 8 bits, 1 kB/s = 8 kbit/s = 8 kb/s. Small and capital 'B's do matter.) Pretty good simple thumb rule is to divide the ISP kbit/s speed by 10 and you arrive at rather suitable kByte/s speed for Vuze. For example, an ADSL with 700 kbit/s upload bandwidth, which corresponds to maybe about 70 kB/s as effective upload capability --> set max. global upload to 65-70 kB/s. That will leave enough bandwidth for web browsing and e-mails. Examples of reasonable settings can be found here: Good settings
After setting the max. speed, the more advanced way is to Use the *built-in auto-speed* functionality. That will sniff your internet connection speed and other usage and will manage the bandwidth that Vuze uses. The basic idea is to prevent Vuze from choking your upload bandwidth with too much traffic, but still try to upload as much as possible.
You can find it in: Tools/Options --> Transfer --> Auto-speed.
You can set it to be active for downloading and seeding and then select either 'Classic' or 'beta' mode.
I personally prefer the autospeed 'Classic' mode, as it can be tinkered to more detail. If you use Auto-speed classic, please remember to also set the max upload speed in its settings. (The 'choking ping time' is the most important tinkering parameter there. It tells the autospeed, how well you want the connection to respond. I have it at 150 ms and decrease step at 13 kB/s to have aggressive speed reduction, if needed.)
My settings for Auto-Speed Classic with 1 Mbit/s upload bandwidth in my internet connection:
Note: one possible reason for Vuze transfers stopping and web browsing slowing, is that you have too many connections, which confuses your router/modem. One symptom is that your modem/router reboots itself, or you need to unplug it for rebooting. You might try to limit 'Max. connections globally' (in Transfer options) to 200 or less, especially if you have one of these routers: Bad_routers
Note: one additional possible reason is the built-in (security) limit for 'half-open' connections built-in Windows TCPIP.SYS drivers since XP SP2 (included in XP SP3, Vista and Windows7 versions). If that is the reason, your Windows Event log contains errors with Event ID 4226 ( http://www.google.com/search?q=event+4226 ). The effect of the limitation can be mitigated by lowering the pace with which Vuze tries to open new connection in boot-up phase. Set the option 'Max simultaneous outbound connection attempts' to 10 or less in Vuze's Advanced Network Settings. There are also 3rd-party patches for TCPIP.SYS drivers, which remove the limits, but you use the patches at your own risk.
Please note, that many useful options discussed here are not shown in the 'Beginner' mode.You have to first set your user proficiency to 'Intermediate' (or Advanced') in Mode page of Options.
Why am I experiencing failed updates?[edit]
Installation of at least one component failed in your config directory there will be an 'update.log' file which contains technical logs on the component update. The newest update is at the bottom of the file, starting with the line 'Update Starts:'. The typical reason for a failure is that you do not have rights to write to folders required for the update.
Note: If the log is of no help to you, you can always send a debug.zip to support via (Help >Generate Debug Info). The debug.zip will contain the update.log. When e-mailing, please indicate that this was a update failure so we know where to look :)
________________________________________Windows Vista users________________________________________
Check on your UAC (User Access Control), this could be preventing you to install updates on your computer. You can try logging in as the Administrator, give write access to directories specified in the 'update.log' file and follow the steps below:
Step 1: Open an Administrator Explorer window
Step 2: Change security settings
Note: You will need to repeat Step 2 for every folder that you need modify access to.
This will open an 'Administrator' explorer window. Every action that you take from this window will be executed with full Administrator permissions. Mac volume booster free download.
If you are still experiencing issues, you can try turning off the UAC. However, Microsoft strongly recommends that you do not disable User Account Control. So to turn UAC off, follow these simple steps:
Note: You will need to restart your computer for the change to take effect. This change affects all accounts on the computer, not just yours.
________________________________________Mac OSX users________________________________________
If you get an error indicating that, for example, '/Volumes/Vuze/Vuze.app/Contents/Resources/Java' isn't writable then you are running Vuze from the wrong location. You need to stop Vuze, move Vuze.app into '/Applications' and then restart it from that location.+
________________________________________Linux/Unix notes________________________________________
If you installed Version 3.0.2.0 or higher, you can also try a manual update.
Assuming you have a ./plugins/azupdater/Updater.jar, this will elevate your rights and apply any updates that couldn't be done with your normal user's rights.
I am getting a 'Disk read error' message when trying to download content, what do I do?[edit]
There are some users who are downloading content and the download goes into that state. Make sure to clear up some space on your hard drive, either by deleting unused files or by clearing up your recycle bin. After you have made enough space on the drive, go back to the Dashboard tab and click on the 'Resume' button.
If you are still receiving errors after freeing up some space on your drive, try doing the following:
It is also possible that an application is trying to access the same file, maybe an indexing service like Google Desktop, etc. Stop the application that is trying to access the Download directly or tell it to skip your download directory. To figure out which application does that use FileMon from Microsoft Sysinternals. To restart a torrent that has this error, just stop the torrent and the click on 'queue' again. I get green smilies but my downloads are still slow[edit]
If you get green smileys as torrents' 'Health', then you know that your basic network settings are ok. However, that doesn't guarantee speedy transfers.
It is good to understand that
It is quite possible with a 'new' torrent or an one with 'small' swarm (only a few peers), that the missing pieces are not available. So, it is quite possible that torrent remains active with 'downloading' status, but is not actively downloading anything as there is nobody to download from.
The low speed or inactivity may also be due to low amount of seeds/peers in the torrent, or their slow upload capability. As there is no central server, your download speed is directly dependent on uploads from others. The torrent's downloaders' total download speed matches the total upload speed.
You can monitor individual torrent's status very well by opening the details for that torrent: UG_Advanced_Information#General_tab
Vuze contains dozens of data items which will help you to understand why a torrent is slow, or why it doesn't progress. The same fields can also be seen in 'My torrents' and 'Detailed list'. You can rather freely select the fields shown by using the Column setup dialog. (For some mystery reason, some of the most useful fields require 'Intermediate' or 'Advanced' user mode, which you can change in Options / Mode.)
Some key fields for torrent status:
A picture of my Vuze shows typical situations with torrents and that the speed vary a lot by individual torrents:
More examples can be found in the Availability article.
In general, many bittorrent client implementation reward good uploaders when selecting data transfer partners, so your upload speed has impact on your download speed. So, having more upload speed in your ADSL/cable connection will also speed your downloads.
Please also understand, that ISPs typically use kilobits/megabits, while Vuze uses kiloBytes by default. 1 Byte = 8 bits, 1 kB/s = 8 kbit/s = 8 kb/s. Small and capital 'B's do matter. If your ISP has promised you a 500 kbit/s connection, you could thus expect max. 62 kB/s downloads..
The downloaded files can be really big. So the download can easily take hours or days with the biggest files.
Traffic shaping:Your ISP may also monitor and throttle bittorrent traffic. Check the Bad ISPs list.If you think you might be blocked/throttled/shaped, you might consider encrypting Vuze traffic: Avoid_traffic_shaping
Please note, that many useful options discussed here are not shown in Vuze's 'Beginner' mode.You have to first set your user proficiency to 'Intermediate' (or Advanced') in Mode page of Options.

Vuze Download Speed SlowTest the speed before complaining[edit]
If you get green smileys as torrents' 'Health', then you know that your basic network settings are ok. However, that doesn't guarantee speedy transfers.
It is good to understand that
It is quite possible with a 'new' torrent or an one with 'small' swarm (only a few peers), that the missing pieces are not available. So, it is quite possible that torrent remains active with 'downloading' status, but is not actively downloading anything as there is nobody to download from.
Before thinking that your configuration is slow, test it with a 'known speedy' torrent. E.g. the following torrent has very high speed: http://releases.ubuntu.com/11.04/ubuntu-11.04-desktop-i386.iso.torrent
It is a Ubuntu Linux distribution, which has lots of seeders, and you should reach your internet connection's maximum speed in most cases (especially with ADSL/cable home connections). Speeds well over 10 Mbit/s (= 1 MB/s as Vuze sees it) should be reachable. You don't have to download the 700 MB torrent completely, but you can use it as a test case for measuring maximum speeds of genuine torrents.
Another user complete download = faster download for you[edit]
Another reason for uploading is simply to help fill everyone up. By doing this you prevent someone, who is seeding, trying to upload a part you already have (and which is useless for you). The chance that he then uploads a piece you need becomes greater. This will not result directly in increasing speed but it will optimize the uploader's upload which results in you getting your piece sooner since you no longer need to wait for a piece. Think of it as a reverse Zero Sum game.
More Things To Know[edit]
It is very important to know that, when you are seeding, or uploading a torrent, the u/l speed of your sharing is not the only thing using your upstream bandwidth. Requests made to the tracker, browser requests to load web pages, and sending email all utilise your upstream capacity. So you may experience the following difficulties when running Azureus.
If you find yourself having problems with the Internet while Azureus is running, try further lowering your max upload.
The point of this section is to explain that when configuring your maximum u/l setting in Azureus, it is best not to set it to use all of your upstream capacity. Rather, it is best to set it to use a maximum of 80% of your total upstream bandwidth.
A note on ADSL speeds using PPPoE:[edit]
An ADSL connection using PPPoE has reduced usable bandwidth compared to the theoretical bandwidth that is purchased. In my experience a theoretical 512kb/s dl product has overheads due to the PPPoE encapsulation that limits the connection to about 400kb/s max. This means the limit before applying the suggestions above should be 400/512 ≈ 78% of the theoretical bandwidth. This logic applies in both directions. So Azureus DL max would be:
80% × 78% × 512kb/s ≈ 319kb/s; 319kb/s ÷ 8 B/b ≈ 40 kB/s if Azureus is the only Internet application.Reduce this somewhat to allow other Internet protocols better response on the same connection.
A tip for RcvWin/TcpWindowSize tweakers[edit]
When you are using a Windows OS you can also use the TCP Optimizer to optimize several system settings for your line speed.
Vuze Download For Windows 10
'I've most often seen [poor performance] with people running on Windows who 'tweak'their TCP send and receive buffers to be very large in search of higherbandwidth. Buffered data is obsolete data and causes serious problemsin the responsiveness of the protocol to changes in the peer state.Since data and requests share the same TCP socket, buffering lots ofdata means that your request for a block may have to wait 10's ofseconds before it even gets transmitted, by which time the peer you aretalking to may have decided that you aren't interested in his data afterall, or your own client may decide that the peer you are talking to issnubbing you. Either of these is disastrous to download rates.'
Final Note:[edit]
Trackers get uncountable numbers of requests made on them every day. I have seen that some people think that clicking on the 'Manual Update' button will somehow increase their speeds or make an offline tracker come back online quicker. It Will Not. Clicking on the Manual Update button is for last resort checking when there is a connection problem On Your End. For example, if you are using a proxy for your tracker requests, you may need to perform some manual announces to verify that the proxy is working while you play with the settings. Also, some private trackers require peers to be logged in on their web page before they can connect to the tracker, adding the IP they logged in from to a whitelist. In this case it may be necessary to announce manually after you log in.
In any case, the more you click on the Manual Update button, the more this will destabilize the tracker, and cause it to go offline for everybody. So for the most part, Leave the Manual Update button alone, and your speeds will recover by themselves (unless there are other issues, but anyway, this button will not help to fix those either).
