I'm running OpenBSD as router; and I see preaks at far beyond 25000
packets per second. with good NICs this is a relatively easy job.
if your cisco now is only equipped with ethernet interfaces I see
absolutely no reason to not use OpenBSD instead.
btw, in my case the hardware is just a Duron 700 (or was it a 650?
something in this range) and it runs at ~ 10% CPU at this load...
cisco notoriously gives its routers too little CPUs. Of course that is
not to force people buy bigger and more expensive routers, who would
