10GE router resource

Wed Mar 26 01:15:57 UTC 2008

Very interesting study I had not seen, and a bummer. That really puts a cramp in my advocation of our CARP+pf load balancers/firewalls/gateways. Than again, what's a PIX box capable of? 

I also had to switch to OpenBSD as there was a fatal crash with the bridge device in FreeBSD when used with my paticular OpenVPN/CARP/pf combination. 

AFAIK pf/forwarding only takes place on one core and wouldn't take advantage of the other 3 cores, correct?

Mike Tancsa did some benchmarking in late 2006:

I think things are slightly faster now but not because of a massive 
change in software architecture.
