[TUTORIAL]Speed up your uTorrent downloads

[Cool Joe]

This is a great way to speed up your torrent downloads, the speed increments are superb!

First of all, if you want to download anything from P2P networks, the best torrent client to use is uTorrent. It's heavy on features, and light on size. As of now, the best version of uTorrent to use is 1.7.7. Get it from here.

Patching the TCP/IP.sys file
By default, windows limits the maximum number of half open connections to 10. There is a patch which increases this limit to 50, thereby increasing the download speed. This will not only speed up torrent downloads, but direct downloads as well.
Get it from here.

Use the right port
This is a very popular tip, but also a very important one. Using the right port number can increase the number of PCs that can connect to you, and thus speed up downloads. It's best to choose a port in the range- 49152-65535. In uTorrent, go to Options -> Preferences -> Connection and enter in number from the above range, and save your changes. To check if the port is forwarded properly, go to Options -> Speed Guide and click on the button “Test if port is forwarded properly”. This will launch the uTorrent port checker webpage that will tell you if the port is open or not.



If the port is forwarded properly, then fine, but if it's not, then you need to do these:-
1. Open the Windows firewall from the control panel, and uncheck the "Don't allow exceptions". You don't have to bother about this if you don't use Windows' firewall. Or if you use a third party firewall, make sure that uTorrent is allowed proper net access.
2. Configure the router to forward the port automatically. There are many tutorials that deal with port forwarding on the net (and this forum itself) so search for them.

Set the proper upload limit
To find out the right number for this, visit Speedtest.net and conduct a speed test. Make sure that there are no applications running in the background which are connecting to the net. Conduct the test a few times and take the average upload speed. Click here and enter the value you got. Change the value in the drop down box to "kilobits". Click on calculate. In the table that appears below, note the value next to "Kilobytes". Multiply this value by 0.8 and you have your magic number. In uTorrent, go to Preferences -> Connection and enter in the new number for the Maximum Upload rate. Leave your download rate at “0″ (maximum).

Change the bittorrent settings
In Options -> Preferences -> BitTorrent you’ll need to make some recommended modifications. Change the settings to make the dialog box look like this.



Enable encryption
In Options -> Preferences -> Advanced you’ll need to make a few adjustments, as well. Scroll down to where it says “net.max_halfopen” and change this from 8 to 50. (If you’re on a dialup Internet connection, don’t do this). Now, scroll up to “bt.connect_speed” and change the value from 20 to 50. Last, go to “diskio.flush_files” and be sure this is set to true. Click Apply and OK to save the changes.

After making these changes, you'll need to restart uTorrent. You'll notice that the speeds have increased substantially (unless you've done some of these tweaks before). Now, with my BSNL Home 500 connection (256 kbps- 2mbps), I get speeds in excess of 200 kbps. In the screenshot, you can see that the speed is just above 200 kbps, but it does get better, and the max I can go is around 256 kbps. I can't get speeds above this because it's just not possible with my connection.

thanks beta testing,
i will try it n let u & every1 know if it really works or not

[Cool Joe]

You're welcome.
And it works 100%, I've tried it myself.

[maxmk]

thanks for the tutorial.. will try it on home PC (in office now)...

[Aakash14]

Really Works !!!!!

[ax3]

thanx .... & whot 2 do if am installing a new softy [upgraded 1] ??

[BBThumbHealer]

Thnx for sharing

This patching TCP/IP.sys file was mentioned by somebody in this forum only..
neways good experiment...

Btw..does utorrent supports broken downloads...for e.g: if i download a file in C: drive (winXP drive) then OS is crashed..but successfully took the backup of the downloaded files (50% completed)..then installed OS again with new utorrent installation...applied same .torrent file but will it continue from dat 50% or will start 2 download all over again

[Abhishek Dwivedi]

wel...all done...no improvement...
may b 'cause i cudnt "Patching the TCP/IP.sys file" as the file which u askd to download made my AVG go crazy ...u sure its not a virus of some kind?...can u gimme a bettr (clean) patching thingy for TCP/IP.sys? BTW am on Dataone 900UL 256kbps

That would be me, I recommend a value of 1000, personally.

It supports broken downloads. Add the same torrent file, and set the download location to the backup location, right click the task and click force recheck.

Not a virus, it goes crazy since you're modifying a system file, that is not supposed to be modified according to AVG. Its very clean, I've been using that site (lvllord.de) for a long time. Just disable AVG.

Adding to the tut, all that stuff about speed testing for maximum upload speed is junk. Just follow my standard 100% working tested values for maximum speed possible in uTorrent:

256 kbps broadband = 5 kBps upload. (Got 30 KBPS with this)
2 mbps broadband = 10 kBps upload. (Getting 250 KBPS with this)

[Abhishek Dwivedi]

stil nt wrking...patch gives an error saying "u do nt have the premissin"...am loggd in as admin...

[dheeraj_kumar]

Disable all antivirus, firewall, antispyware, etc and try it once again.

You should have your download limit more than 5 because if ur upload rate is below 5 or equals 5, your download rate is restricted by 6 times of upload rate.

eg. 5kbps upload will restrict to a maximum download speed of 5x6=30kbps
while 4 kbps will give a download of 4x6=24 kbps

so for better download speeds it should be 6 or more. I use a figure of 7.

stil nt wrking...patch gives an error saying "u do nt have the premissin"...am loggd in as admin..

You don't need to do it through a software you can do it manually.

Just go to preferences and click on advance(not on the UI extras and Disk catche) Click over Advanced now on right window you get a list of different advance options . change the value of net max half open to the desired value.

I got the maximum speed of 212 kbps.

One more thing to do all the setting automatically leaving the half open issue.
Do
Click on
Options--> Speed Guide--> Connection type --> now select the speed of you connection eg I chosed
xx256k.
Now all the required settings will be done automatically.
Now if you are on a limited plan like me then change the upload limit from 22(depends on your selection) preferences-->Bandwith-->Maximum upload limit to 7 .

Hope I understood right and responsed well.

Well this didn't worked for me much but this sure works BUT all they do is increase Upload speeds. Check this out too

How can you come to this conclusion??

@all the others- Your queries have been answered by le dheeraj_kumar.

so for better download speeds it should be 6 or more. I use a figure of 7.

In a 256 kbps connection, theoritical maximum download speed = 256/8 = 32 KBPS. I dont understand the math you do, but from experience, I set the global upload speed values from 1 to 10 KBPS, and got the best results of 30 KBPS (out of 32) at 5 KBPS upload speed.

Similarly, In a 2 mbps connection, theoritical maximum download speed = 2 * 1024 / 8 = 256 KBPS. I got the best results of 250 KBPS (out of 256) at 10 KBPS upload speed.

I tested them both in BSNL 500 plan, first it was 256 kbps, then they upgraded it to 2 mbps. They were tested using uTorrent, whatever was the latest version at that time, using highly seeded torrents from PirateBay Games, MiniNova TV Shows+Movies and Dattebayo's Naruto Torrents, where seeds are 10000-30000 and leeches were like 2000-5000.

Even now, I'm using a global max upload of 10 KBPS in the latest uTorrent, BSNL 2 mbps broadband.

Because Speed tests normally show a high upload speed, and setting around that value in uTorrent will only decrease the speed. The best way of finding your optimal maximum upload speed is:

1. Get a highly seeded, lowly leeched torrent - like a linux distribution or a TV show.
2. Set the global max upload speed at 1 KBPS. Start the torrent.
3. Download it for five minutes, noting the maximum download speed attained.
4. Dont stop the torrent, but increase the speed to 2 KBPS. Watch as the max download speed increases automatically.
5. Continue increasing till the download speed goes near your maximum possible download speed for your connection.
6. Thats probably your optimal value, to test that value further more, increase it by 1 more KBPS, and watch as the download speed drops down.

It would take around 30 minutes to find the optimal speed, and you can use that value on any internet connection of your same speed after that. Thats why I suggested the 5 and 10 KBPS.

[Cool Joe]

^^Thanks for the clarification. I feel this sounds more rational.

Terrible failure,,,,,,,,,,,,,,,,..............,,,,,,,,,,,,
just increased 3KBPS !
dont tell me it is not seeded.
27 seeds and 1056 peers

[Abhishek Dwivedi]

right..am getting 30KBps...i always used to get this speed on ma BSNL 256kbps (sometimes 32-40KBps also...dnt ask me how)...

[hsr]

but the prob is that i r on 2mbps!

Even though there are 27 seeds, note that there are 1057 peers and many of them may be leechers, so you're not getting good DL speeds. And to get good DL speeds, you need a good number of connected seeders like 60+. So try some other legal torrent.

Did you try everything?? And also try dheeraj_kumar's advice to get the right upload limit.

[Psychosocial]

Thanks...... but I am getting 28-30kB/s already on a 256kbps (32kB/s max) connection .

But it will help the ones with 2mbps plans.

[Cool Joe]

Thanks you all for your comments.

[Plasma_Snake]

Welll mine is a 512Kbps UL connection and now today after deleting, rebooting, and creating a new connection, I'm getting 60-62KBps !

[maxmk]

It works thanks...

[hsr]

60+ seeds right? how about this?

~sniped~

but stll the speed is 34 max

[zyberboy]

but stll the speed is 34 max

u need upload for u to download frm torrents,ur status shows tracker error

[hsr]

you see, it just came in that time.
but the sppeds are still 34 !

[Cool Joe]

@hari- What plan are you on???
Have you disabled any firewall that you're using??? Even the Windows firewall can reduce your speeds....
And plz don't post such screenshots here. It's not good for this thread. Plz remove the screenshot or snip the names of the torrents.

[hsr]

me on H500
