i am pretty sure the best speeds u can get with torrents would be similar to pure HTTP/FTP based downloads from good servers using a decent download manager.
unless of course, the file is being downloaded by someone on your local network.
Besides forwarding the port & patching the TCP/IP connection from default 10 to a much higher number(100), the only way the torrent downloads be fast is when there are more seeds than lechers, and also depends the other peoples "upload rate" . If they have good upload speed only then will you be able to download faster.
OLD GUIDE, BUT USEFUL
Note:Some of the settings mentioned below are optimized for 256k connection. If you want to calculate the optimal settings for your connection, check at the end of this tutorial. But I suggest you to read the entire tutorial for guidance on other settings.
First go to Options>Preferences>Network
1.Under ‘Port used for incomming connections‘ enter any port number. It is best to use a port number above 10000. I use 45682.
2.Randomize port each time ?torrent starts: UNCHECKED
leave this unchecked because if u have
router. If you do not have a router or a firewall, and want extra security,check this option.
3.Enable UPnP port mapping (
Windows Xp or later only): UNCHECKED
leave this unchecked because I have experienced it slowing down speeds. It is not needed if you manually port forward.
4.Add ?torrent to Windows Firewall exceptions (Windows XP SP2 or later only): UNCHECKED (do this only if you have windows firewall disabled)
5.Global Maximum upload rate (kb/s): [0: unlimited]: 22 (for 256k connection)
6.Protocol Encryption: ENABLED
I would recommend everyone to enable this. This can help increase speeds with many ISPs.
7.Allow incoming Legacy Connections: Off

Options>Preferences>Torrents
1.Global Maximum Number of Connections: 130 (for 256k connection)
This number should not be set too low or the number of connections made to your torrents will be limited. Setting it too high may cause too much bandwidth to be used and can cause slowdowns.
2.Maximum Number of connected peers per torrent: 70 (for 256k connection)
If you see that the peers connected to a specific torrent are exactly this number, or very close, increase this number to improve speeds.
3.Number of upload slots per torrent: 3 (for 256k connection)
This depends on how much you want to upload to other users. Do not set too low or it may affect download speeds.
4.Use additional upload slots if upload speed Preferences>Advanced
If you use Windows XP SP2, patch tcpip.sys with LvlLord’s Event ID 4226 Patcher to get better performance.
net.max_halfopen: 50
DO NOT CHANGE THIS OPTION unless you have Windows XP SP2 and have patched tcpip.sys.
You can also patch tcpip.sys with xp-Antispy
If you have a firewall…
Open up the options/preferences/settings for the firewall - usually your firewall will have an icon to click in the taskbar
Look for the keywords “allow list” or “programs”
Add the application you want to give access to the internet
Make sure to save your settings when you are done
If you have a router…
Go to start>run>type cmd, press enter>type ipconfig, press enter
Remember both your ip address and your default gateway
Type in your default gateway into your default browser, a password prompt may come up. The default username and password are admin for my router
Under ‘Applications’ fill out one line for each p2p client you use
You need to use your ip address, the correct port range and set either tcp or udp
You can find and change the ports in the actual p2p client’s settings, just make sure they are the same in the router
Most p2p apps need both tcp and udp checked, if you are not sure check your p2p client’s FAQ
