Two items: 1) I have noticed something similar to rafi's peak scenario, although it seems to happen as the torrent is contunally running. WHat it does is it will increase in speed and then all of a sudden drop back to where it was, and it does this continually. After a few minutes or so it evens out and sticks to the slower speed. 1.1) Sometimes it does exactly what rafi is describing. 2) I have noticed that I have to keep the upload slower then what I want it to be at otherwise it transfers too fast and screws over the download. Its like the original case, where the overhead was causing issues, but not as harsh. I have net.calc_overhead set to true and it improves it but there is a difference. For example the upload rate of 27.7 kB/sec in μTorrent is reading as 31.6 from a throughput meter. μTorrent also never hits my throttle amount of 30 kB/sec, 28 is as close as it gets. Scott
