Are you sure you have the ports and the NICs all in full duplex ? Try setting the switch *manually* to 100baseTX full duplex (ie speed 100 duplex full on the relavant switch ports. Then on the FreeBSD boxes ifconfig fxp0 media 100baseTX mediaopt full-duplex on both machines, and run your tests again. ---Mike Mike Tancsa (mdtancsa@sentex.net) =09 Sentex Communications Corp, =09 Waterloo, Ontario, Canada "Given enough time, 100 monkeys on 100 routers=20 could setup a national IP network."
