Switeck Posted November 22, 2009 Report Share Posted November 22, 2009 Maybe you're making unreasonable assumptions about the speed of your internet connection?...Or you're getting disk overload error messages (bottom left of uTorrent window)?

Firon Posted November 22, 2009 Report Share Posted November 22, 2009 What is your real connection speed? And what are your settings? Link to comment Share on other sites More sharing options...
spx Posted November 22, 2009 Author Report Share Posted November 22, 2009 disk is not overloadedreal connection speed: 100mbits on ISP's LAN and on city traffic-exchange (most active torrents you see on screenshot are city-IX), 7 mbits on all other resources.max number of connections: 100connected peers per torrent: 10upload slots: 10net.low_cpu = falseok, and also i see now that changing bt.transp_disposition didn't not fixed local peer problems:http://img121.imageshack.us/img121/8071/19800653.pngi 've readed my "main" tracker topics about uTorrent and "wavering" speed, and here is result:i'm not alone with that problem - first time when problem has been detected was a moment when people upgraded from 1.8.2 to 1.8.3. They are saying, that when they downgraded to 1.8.2, everything changed back to normal state. Link to comment Share on other sites More sharing options...
Switeck Posted November 22, 2009 Report Share Posted November 22, 2009 Have you tried disabling UPnP, NAT-PMP, and Resolve IPs?Lowered bt.connect_speed to only attempting 1-4 outgoing peer/seed connections per second?(Incoming connections do not count against that limit.)Are you disconnecting from peers/seeds quickly or often?Your real max international upload seems to only be about 2 megabit/sec (200-something KiloBYTES/second on your speed graph). Setting upload max to 2000 KiloBYTES/second probably aggravates the problem and triggers the wavy resulting speeds.Posts with similar problems mentioned:http://forum.utorrent.com/viewtopic.php?id=54379http://forum.utorrent.com/viewtopic.php?id=56580http://forum.utorrent.com/viewtopic.php?id=56897 Link to comment Share on other sites More sharing options...
spx Posted November 24, 2009 Author Report Share Posted November 24, 2009 It's very strange, but now everything is ok - i can't even start changing any settings to check the speed graph, because i won't see the differene - speed is approximately constantUPnP, NAT-PMP - disabledResolve IPs - enabled bt.connect_speed - 20peers, who are connected via ipv6 are disconnecting and reconnecing often and usually have low speed. ipv4's are ok.no, my real international speed is not 2mbit - it's 7, i have checked and rechecked that.also, i already said, that most connections on my first screenshot were city-IX, not international.Maybe, the problem is causing by overloaded city traffic exchange point, because i have secondary uTorrent, which is running for "international" trackers - and it works ok with same settings. i should check it out.

Switeck Posted November 24, 2009 Report Share Posted November 24, 2009 Your picture of uTorrent's speed graph showed upload speed getting "stuck" at less than 250 KiloBYTES/second (2 megabit/second). What caused that? Link to comment Share on other sites More sharing options...
spx Posted November 24, 2009 Author Report Share Posted November 24, 2009 as i said, i dont know (i didn't change anything since i changed bt.transp_disposition), and i cant test it since speed became normal. but, it would be safe to say that it's not my isp's international speed problem - here is my secondary uT, which works only for international torrents:http://img522.imageshack.us/img522/6931/53815240.pngas i mentioned above, most connections at first screenshot were city-IX, so it may be exchange point problem. but, it not solves the local peer problem at post #4 ( http://img121.imageshack.us/img121/8071/19800653.png )i have no local speed problems, so probably it caused by uT or it's settings, finally.--updoh, wait.. i think i've changed queueing settings a few moments after changing bt.transp_disposition... they were about 50 active torrents / 15 dl torrents (i don't remember)and now it's 300 active and 100 downloading..but i don't know how it could corrupt my speed, because i had less than 50 active torrents that moment.

Switeck Posted November 25, 2009 Report Share Posted November 25, 2009 Setting queueing that high may trigger a bug in uTorrent for all I know. Link to comment Share on other sites More sharing options...
