darczon69 Posted May 14, 2011 Report Share Posted May 14, 2011 Hello,I seem to be having a very peculiar problem. I have more than 700 torrents seeding (100+ active at any time). My problem is as follows:If I keep all my torrents on seeding duty, my global upload speed drops to 500 kb/s. If I keep active a small portion of the torrents (10-15) my global upload speed goes back to 6 mb/s. I've made several experiments to be sure it's not about the fact that upload speed is divided by the number of torrents active. For example, I downloaded a torrent (let's call it torrent A) and I kept it seeding. If only 15 torrents were active, torrent A would register a 3,5 mb/s upload speed (6 mb/s global speed). After activating the rest of the torrents, torrent A's upload speed dropped to 200 kb/s while the global speed was around 550 kb/s.My question is: why is my global upload speed so low if I activate multiple torrents? As a side note, I don't have any download speed problems.Any help will be greatly appreciated. Link to comment Share on other sites More sharing options...
DreadWingKnight Posted May 14, 2011 Report Share Posted May 14, 2011 My question is: why is my global upload speed so low if I activate multiple torrents? Disk thrashing. You're trying to access pieces from more files and more places on the disk than is possible to cache into memory. Link to comment Share on other sites More sharing options...
darczon69 Posted May 14, 2011 Author Report Share Posted May 14, 2011 And do I solve this problem by allowing utorrent to use more memory? Link to comment Share on other sites More sharing options...
DreadWingKnight Posted May 14, 2011 Report Share Posted May 14, 2011 No, you'll only slow down the effect happening (best case scenario).Treating BitTorrent like it were a traditional p2p program like kazaa just makes it perform horrendously.

darczon69 Posted May 14, 2011 Author Report Share Posted May 14, 2011 Aha. I understand. Thank you.Then, what is the best course of action? Link to comment Share on other sites More sharing options...
DreadWingKnight Posted May 14, 2011 Report Share Posted May 14, 2011 Run fewer torrents at a time, and let uTorrent cycle them on its own. Link to comment Share on other sites More sharing options...
darczon69 Posted May 14, 2011 Author Report Share Posted May 14, 2011 I understand. So there's no way I can keep them all active...Thank you for all your help. This topic can be closed now. Link to comment Share on other sites More sharing options...
