Our investigations so far showed that bittorrent is only good if the
files to be transferred fit well into main memory. If you exceed about
90-95% of the RAM your disks will be accessed a lot and the performance
breaks down a lot (we have seen close to wirespeed in the beginning and
in the end we were crawling with mere few 10 kByte/s).

Cheers

Carsten
