I tested Linux in bridge configuration with the same machine and it CPUed out at about 600kpps through the bridge.. That's a bit low :/ Soft interrupt using all the cpu. Same opteron 2222, 82571EB Pci express NIC. Tried SMP/ non-smp , load balanced irqs, etc.. Good news is using iptables only adds a few percentage onto the CPU usage. But still, what's with that.. So far FreeBSD got the highest pps rating for forwarding. I haven't tried bridge mode. Ipfw probably takes a big hit in that too though. Looking for an 82575 to test.. Paul
