syberjj Posted April 17, 2010 Report Share Posted April 17, 2010 I was having lots of problems with utorrent.Uploads were going well, but downloads were dieing off allot. It started and already went down to 0.x kb/s and then disconnected from the peers.So I have this download open, and it is going at UNDER 10kb/s and 3 SECONDS after I change bt.tcp_rate_control to false my download speed is over 100kb/swhat is this setting and why is it fucking up my downloads?PS: I live in brazil, my provider is "NET serviços de telecomunicação" and this is my average speed result:http://www.speedtest.net/result/784939690.png Link to comment Share on other sites More sharing options...
Switeck Posted April 17, 2010 Report Share Posted April 17, 2010 It's important enough to be mentioned in 1st link of my signature...http://forum.utorrent.com/viewtopic.php?pid=258232#p258232"Try disabling bt.tcp_rate_control? (Can be found in Preferences > Advanced)"I believe it was discussed in the v1.9 and v2.0 announcement message threads in the "Announcements" forum:http://forum.utorrent.com/viewforum.php?id=4 Link to comment Share on other sites More sharing options...
Ultima Posted April 17, 2010 Report Share Posted April 17, 2010 Because bt.tcp_rate_control is explicitly used to throttle TCP connections based on delay information gathered over uTP. It is hardly perfect though, which tends to slow connections down more drastically than it probably should at times (or sometimes doesn't throttle back enough).What version of µTorrent?

syberjj Posted April 18, 2010 Author Report Share Posted April 18, 2010 v2.0I don't always have this problem, but more and more often.Is there some way my ISP could actively "exploit" to get uTP to slow my traffic?You guys should look into that, because even if uTP is there to help everyone (specially the ISP's) they shouldn't be able to do something like that.Is there any way to check if my ISP could be doing that?thanks Link to comment Share on other sites More sharing options...
Switeck Posted April 18, 2010 Report Share Posted April 18, 2010 In theory, a QoS shaper (that regulates uTP to scavenger bandwidth only) could cripple uTP speeds during congestion on the line. There would be no way whatsoever to detect that cause specifically. uTorrent would download/upload slower, but quite likely it wouldn't be the only thing!

syberjj Posted April 19, 2010 Author Report Share Posted April 19, 2010 oh, I have QoS shaping activated in my local network. I use it to attribute minimum rates to each machine (the voip phone gets a minimum download/upload rate and so on).Is uTP incompatible with that?

Switeck Posted April 19, 2010 Report Share Posted April 19, 2010 QoS shaping could work with uTP if it can handle large numbers of UDP packets quickly. Link to comment Share on other sites More sharing options...
syberjj Posted April 22, 2010 Author Report Share Posted April 22, 2010 I am using an AProuter 254 router / WiFi spot. I never had performance issues with it before... Link to comment Share on other sites More sharing options...
Switeck Posted April 22, 2010 Report Share Posted April 22, 2010 Did you map uTorrent's outgoing ports to a consistent port range for QoS purposes? Link to comment Share on other sites More sharing options...
