Bernard, I did some tests and also with my rtl8139 card I found the same slowness using rsync. I didn't notice that because for my previous tests I always used bittorrent. In fact the strange thing is that other protocols doesn't seem to be affected to that slowness!! Moreover it doesn't seem to be a network issue. I tried also to copy a file locally in the client and it gives the same performance over the network (from 500KB/s up to max 1MB/s). So it seems that the process is CPU bound and not I/O bound... and the problem seems to happen only with 2.6.16 kernel (with another kernel performance are great as usual!)
I'm trying to figure where exactly is the problem...
