Forgive me if this isn't directly pf related, but I think you folks
would have some experience with this issue. What is the minimum CPU
required to saturate a 100mbps ethernet? My firewall is a 166mhz
pentium that maxes out at 30-40mbps on the internal interface (using
either fxp or xl cards), and doing a systat -vmstat while testing with
ttcp shows that the CPU spikes up to 80-90% in use. First I thought it
was a faulty card, but now I think that the 166mhz pentium doesn't have
enough power to saturate the link. I have an old starmax 200mhz 604e
which is able to reach close to 100mbps in the ttcp test, and my other,
faster internal machines have no problem saturating the ethernet
(switched network).
Is 166mhz just too slow?
