Maximizing uTorrent speed

Updated on January 23, 2013

About This Article

In this article you will learn step by step how to customize your utorrent and get more download speed. Additionally you will learn how to get more seeds and peers, patching tcpip etc. If you follow this article I am sure you will get a whole new experience of using utorrent.


The Torrent Client

If you do not have a torrent client software then my personal recommendation is utorrent. Visit this page to download the latest utorrent client software.


The speed test

If you are not sure of your download/upload speeds, then visit to run a speed test. The defult Server (golden pyramid) works out
most of the time. Or you can select 2 or 3 different server around you to find out the mean result.

Note down the Download and Upload speed including the unit (e.g kbps/mbps); You will
need them later.

Step 3. Select your connection type or upload speed from the preset list.

  • Your connection should be near to one of the categories.
  • You can easily select your connection type from the upload speed result you get from the

e.g "xx/384k" means that your download speed unlimited and your upload speed is 384kbps.

  • uTorrent will automatically adjusts the "Affected Settings" area with recommended values for your upload speed.

Step 4. Click on "Use Selected Settings" button. On the newer version click "save&close" button.

The Speed Guide configuring is complete.

Half-open limit fix

Advance Configuration

Step 1. Patching tcpip.sys (Only required for Win XP and Vista. Not needed for Win 7)

  • Half-open limit fix is a good utility to patch tcpip.sys To download it go to (current version 4.2)
  • Download the zip file and extract all files into a folder.
  • Open the folder and right click on Half-open limit fix.exe file then select run as administrator.
  • On the window, first you will see the current half-open connections.
  • Enter 100 in the new value section and the click "add to tcpip.sys"
  • Restart your computer.
  • If something does not work properly and you want to undo the changes then run the software again and then click "Restore original file"

Advanced menu

Step 2. Configuring utorrent

(Use this only if your version is older than 2.x.x)

Now that you have patched the tcpip.sys it is time to configure utorrent.

  • Run utorrent.
  • Click on options then preference.
  • Click on Advanced on the left column.
  • Look for "net.max_halfopen".
  • Change "net.max_halfopen" value to 50 then click set.
  • Now click Ok.
  • Select all the torrent and stop them.
  • After 10 seconds start them and watch the speed.

Note: An asasterisk (*) will appear when something is changed from its defult value.

You can add more trackers in two way.

2. Download public tracker list

  • To get the tracker list go to the link below

  • Download the "public tracker list.txt" file in your computer.
  • Run utorrent.
  • Now right click on the torrent you want to add tracker.
  • Click properties.
  • You will see some trackers under General tab.
  • Copy the text from the file and paste it at the end of previous tracker list.
  • Now click on the tracker tab and check if there is any tracker listed twice. If there is any then remove one by right click on it and then click "Remove Tracker".

You will get much more seeds and peers.

Best Trcker List

This tracker list is my personal favorite. This list contain few tracker but works very good.

Download this tracker list and add them in the torrent properties. Do not replace previous trackers. Add them at the end after a blank line.

If you do not understand anything or have anything to know about please leave a comment or question. Please share your trackers also with us.

Thank you.

      Am a S -class utorrent user, am going through the comment and I see that ppl using certain settings getting 150kbs, personally I think your speeds is incredible slow, with perfect settings matching for utorrent, average speed should be 2.2mb/sec. I top like 9mbs a sec, downloading a full season in 10mins and movies or 1gb files in 2mins or less. So congrats to the utorrent team, awesome job!

      Pretty good hub. I've used uTorrent for a while and have used a few of these tricks. You should write a hub about how to download torrents anonymously if you haven't already.
