Maximizing uTorrent speed

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.

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.

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.

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.

Thanks for this great idea. I can't wait to try it out.

Sample 2 years ago

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!
