Thank you all for your help. I've finally found the bottleneck: the onboard PowerMac ethernet port. After verification, changing network cables was not an option, I've used on this connection a cat. 7 network cable. I've connected the em0 port of the freebsd box on a gigabit PCI-X NIC I have in the Mac, and given a second try to the "dd | nc" client/ server bench: 103 MB/s. This is far better ! Same setup with apache 1.3 on the mac, wget on the Freebsd: about 40 MB/s (350 MB file) The PCI-X NIC has flow-control enabled: media: autoselect (1000baseT <full-duplex,flow-control>) status: active I'll check later the influence of this parameter. Again, thank you all for your replies patpro
