ASDF Commander Posted October 21, 2005 Report Share Posted October 21, 2005 Consistently with µtorrent I can only upload to about half my potential. As soon as I switch back to Azureus, my upload rates will go back to max within seconds for the same torrents. I really like this client, but upload rate is important to me. I'm just making this post to inform the developers of this issue. I have everything set correctly and have tested to make sure my BT ports have been correctly forwarded. Download rates are just dandy though BTW.Thanks Link to comment Share on other sites More sharing options...

frankw Posted October 21, 2005 Report Share Posted October 21, 2005 My upload rate is consistently around 1KB/s with a maximum of 20KB/s. I have increased the upload slots from 4 to 10 per torrent, and not seeing any obvious difference. Link to comment Share on other sites More sharing options...

sethg Posted October 21, 2005 Report Share Posted October 21, 2005 Vurlix, are we keeping the outgoing TCP buffers full? While the upload speed depends on the peer at the other end of the TCP connection, as well, if we let the buffer run dry we will never have a good upload rate. Some peers seem to make requests for only a couple of pieces at a time and make more frequent requests.I only suspect this because I notice how slowly the upload speed ramps up, even after I see requests for pieces from the peer.

ASDF Commander Posted October 21, 2005 Author Report Share Posted October 21, 2005 Try increasing your upload slots per torrent to 8 or 10That might increase my upload, but I really don't see that as a solution. I like to have a generous KB/s to peer ratio because sometime when I need low network latency, I will lower my upload cap. If I were to increase my slots per torrent that would probably put me in snub territory when my upload is halved.Do you know of anything that might be preventing utorrent from uploading at full speed to a peer? I seem to have good, long connections for all upload slots, just not to full bandwidth. Thanks for replying. Link to comment Share on other sites More sharing options...
vurlix Posted October 21, 2005 Report Share Posted October 21, 2005 No idea. I always max out my connection's upload rate (~90 KB/s)... I don't think µTorrent itself has any problems uploading.. for me, at least, that's the case. Link to comment Share on other sites More sharing options...

I don't think µTorrent itself has any problems uploading.. for me, at least, that's the case.I see the same thing in seeding mode, where we have a maintained connection and the peer at the other end is not going to drop a seeder.The problem is during downloading, where we are only connected to a few peers and they can choose to choke us if we don't upload faster than their other peers. I sometimes see peers that request few pieces but do it more often. We seem to have trouble ramping up to speed quickly, but I can't say which end of the TCP connection is the problem. That's why I ask how much effort we put into keeping the outgoing TCP buffers full, or at least always one packet's worth of information so they don't run dry. Depending on the data rate and buffer size, we have to get back there often enough. Not being a Windows software type, I don't know if you get interrupts when the buffer is half-empty, empty or whether the interface is polled and you don't get any interrupts.

chaosblade Posted October 21, 2005 Report Share Posted October 21, 2005 Yeah, BitComet has both lazy bitfield (i think, not sure) and header encryption. Link to comment Share on other sites More sharing options...
