Rule of thumb is roughly one GHz per Gbit of traffic, if the only thing it's going through is the routing table. You're well over that, so something is probably wrong. I'd be looking hard at your network devices and motherboard. > I have a couple of questions : > > 1) Does anyone know if there is any significant different in > performance between routing and bridging packets in Linux ?

There is no fundamental performance difference between the routing and bridging code, but your specific configuration may have one. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
