This certainly suggests that CPU on the athlon is not your limiting factor. > to be honest I was expecting a lot more. > > I am using an 8 port SMC gigabit switch that supports jumbo frames - how do > I increase the ethernet frame size on the firewall interface ? I believe there is a hidden option to change MTU - I'll leave it to someone else to provide that option. > I'll see if I can rig up an extra long crossover cable to bypass the switch. > > If I am supposed to see 400 megabits, then I presume this is split between > the incoming nic and outgoing nic, so 200 megabits per second ?? No, that's 400Mbit throughput :) A [EMAIL PROTECTED] bus is roughly around 1Gbit transfer rate so 500Mbit would be the absolute max. > Any ideas where I should be checking ? netstat -ni from the shell and see if you're taking any interface errors on all the machines involved in the test. --Bill
