colweb Posted November 4, 2007 Report Share Posted November 4, 2007 When I seed 2 torrents (let's say X and Y) the total upload speed is never goes over 80kb/sec. But my max upload speed is 96kb/sec. So I tried this,On the same machine started vmware and in vmware installed another win-xp. Then I started torrent X from the main win-xp and torrent Y from the virtual win-xp. When I look at the combined upload speed is comes close to 94kb/sec.When I only let torrent X run the upload speed for this torrent goes up, but still not higher then about 80kb/sec.So, when seeding only 1 torrent, the upload speed is about 83% of max bandwidth. When seeding 2 torrents from 2 machines the upload speed goes up to about 97.9% of max bandwidth (even if one machine is virtual). In all running uTorrent's I have not limited the upload/download speed.Its hardly unlikely that the amount of leechers is to blaim. In all instances there where over 100 leechers reported by the tracker and between 10 to 28 (per torrent) connected with me. Torrent X and Y were both very big (over 10GB) so seeding took time enough to do this test.Can somebody explain this speed difference? Link to comment Share on other sites More sharing options...
Switeck Posted November 4, 2007 Report Share Posted November 4, 2007 Try upload speed limited to 90 KiloBYTES/sec in µTorrent and see if you can run 1 µTorrent client by itself. Link to comment Share on other sites More sharing options...
colweb Posted November 4, 2007 Author Report Share Posted November 4, 2007 Currently running 1 uTorrent and have the upload speed limited to 90kb/sec. It's running like this for 20 minutes and it seems the speed drops to an average of 70kb/sec. I thought uTorrent would use 100% bandwidth if possible and detect it when another program (like Firefox) tries to use the internet connection, so it can drop its speed.Could it be that uTorrent is programmed to never go faster than about 80% of max upload speed? And only when running 2 clients go over 80%? Link to comment Share on other sites More sharing options...
Switeck Posted November 4, 2007 Report Share Posted November 4, 2007 Tell me ALL the settings you're using as shown by Speed Guide (CTRL+G)...bad combinations give very bad results. Link to comment Share on other sites More sharing options...

Ultima Posted November 6, 2007 Report Share Posted November 6, 2007 And those are very bad settings. Run the Speed Guide properly (read the instructions more carefully). Link to comment Share on other sites More sharing options...

colweb Posted November 8, 2007 Author Report Share Posted November 8, 2007 Sorry for the very late reply. I have changed the settings and the upload speed comes close to 96kb/sec. Thanks. Link to comment Share on other sites More sharing options...
