It is not irrelevant which protocol you use to copy large files. Some protocols has less overhead. Also, you may experience better performance between bsd stations, if you can try set up two bsd stations to test performance on different protocols, ftp, http, tftp, whatever. I think the best I have had on a 10Mbit/s was 1Mbyte/s - that is about 80% is actually effective payload. Another thing you can do to get more correct numbers is to use the packet filtering statistics. Cheers, Erik
