i'm going at 34kbps on torrents and i'm at 89%. i'm uploading around 50kbps and i will seed as long as possible. when i first started downloading it was about 40% seeds and 60% leechers then when i woke up this morning it was 9% seeds (according to linuxtracker).. people need to stop deleting torrents after downloading when there's a high demand and a low number of seeds.
senofed are you using azureus? You can adapt your upload traffic to less than you downloadtraffic.
There is a settings menu somewhere, and a help section that says useful things about available bandwidth.
Azureus - you can just right click on the torrent and adjust the speeds of download and upload. People have to seed and share, at least share what you download for a 1:1 ratio. Between the x86 and 64 I have uploaded over 10 GBs. Every seed counts.
