Assuming that you're talking about MBytes/sec there is a chance that your network link is using 100 MBit/sec full-duplex mode instead of 1Gbit/sec. Try to do 'ifconfig | grep media' on the FreeBSD box and watch for the speed regime specification. > The other machine doing the transfers has similar specs (same > Ethernet Card) but is a Windows XP box. Windows should report the interface speed too: unplug the cable, plug it again and watch for the fancy popup on the taskbar. Or check the interface properties box. -- Eygene
