Many ISP’s are limiting or throttling P2P traffic on their networks. By throttling BitTorrent traffic the speed of BitTorrent downloads decrease, and high speed downloads are out of the question. In this tutorial I will tell you how to avoid traffic shaping on Azureus!
1.
Go to: Tools > Options > Connection > Transport Encryption
2.
Check the ‘require encrypted transport’ box.
3.
Choose RC4 in the ‘minimum encryption’ dropdown box
RC4 uses more CPU time than the plain encryption or no encryption. It is however harder to identify for traffic shaping devices. You can check your CPU Usage through the Windows Task Manager (Alt+Ctrl+Delete)
4.
You can choose to tick the ‘Allow non-encrypted outgoing connections if encrypted connection attempt fails’ box. This will ensure compatibility with clients that are not using encryption. However, it makes it easier for your ISP to detect BitTorrent traffic. I recommend that you try to tick this box first. If you are still not getting proper speeds untick it
5.
Tick the ‘Allow non-encrypted incoming connections’ box

Ok, that’s all.. easy right?

Do you have to stop & re-start your torrents and/or do you have to stop & re-start Azureus???
Is this tweak applied automatically?

Didn’t work for me either. Apparently some ISPs are using more sophisticated techniques to identify p2p traffic than others.
