Huge bandwidth overuse in utorrent / bittorent

[iWonder]

Hi,

I found out that at the last few months there's a huge bandwidth overuse of those clients, and what I mean by that is when the clients upload at lets say 50KB/s the actual network use is more than 80KB/s.

My internet connection is 10/0.8Mbps.

I have been using the torrent program for a few years now and I've noticed this problem only at the last few months.

Usually my client's upload speed was about 100KB/s (which suits the network bandwidth) but now it(the client) simply cannot reach over 70KB/s upload speed since it overuses the bandwidth.

Even if I limit the client to 30KB/s upload speed the actual network use is more than 50KB/s.

This happens when use the same settings which i've been using all these years:

Max global connections - 200

Max # of connected peers per torrent - 50

# of upload slots per torrent - 5 And I do not use the additional upload slots option.

This happens even if I have less than 3 torrents seeding and not downloading.

My ISP connection is a special "Gamers" account which doesn't suffer from throttling and I am able to reach the maximum dl/up speeds most of the time.

I hope this is enough info for you to check this out.

Please note that this was tested on several PC's and different network hardware.

bt.ratelimit_tcp_only is set to what in advanced?

If you turn off the apply rate limit to uTP, does it reach your line's upload limit?

[iWonder]

bt.ratelimit_tcp_only = false

I haven't seen any difference when setting 'apply rate limit to uTP' to OFF, but I can check it again.

Thanks for the help btw!

Turning off the apply limit to uTP didn't help, the client still shows upload of 20KB/s while the internet bandwidth is at 40-50KB/s..

any ideas ?
