The server (192.168.1.200) is FreeBSD 5.4 with Duron 900 and 3C905C The 3com 3c905 is not a very good card under FreeBSD the driver was written without support from 3com and is shakey on a lot of hardware. I would say there's a big question that your server is actually saturating the ethernet. Probably that is why your only getting 90Mbt. >NIC; router is m0n0wall (FreeBSD 4.11) with three Intel >Pro/100S Nics and >Celeron 433; The user computer (192.168.10.249) is Celeron 2400 >with winxp >and integrated NIC Realtek 8139 series.
