I spent some time tuning the vr(4) driver on ALIX a while back[1], and in my experience the throughput maxes out at around 85 Mbit/s of TCP (ie iperf) traffic through it. I don't know what the limiting factor is, but it's not CPU. My guess is it's the checksum offload hardware in the chips, in which case doing those in software would be faster at the cost of using more CPU, but I never tested this theory.
