I think that packets per second is just as important as megabits per second when evaluating routing. We are a wholesale VoIP operator, so we switch many small packets (less than 100 bytes each) - it takes almost as much CPU power to make routing decisions for a 100 byte packet as for a 1500 byte FTP packet. You will find much of the Cisco specs talk about throughput in packets per second (pps, or kpps). The NIC I am using is the built in Intel i82555 in a DL360 1U server. According to vlan(4), the fxp driver doesn't do native VLAN, but can do large MTU for VLAN tagging. This should give enough performance for our initial requirements (up to 10mbit) and I'll review it later. I'm also curious about whether FreeBSD supports polled rather than interrupt driven behaviour in the NIC driver - that means that the system won't keep on re-entering an interrupt handler concurrently while under load (when a DoS attack is in progress). The server will be set up tommorrow - I'll do some tests and publish my experiences on my web site, as I know several of my customers want to duplicate this for their own redundancy plans.
