I'm so glad that I both figured out how to make this a heck of a lot faster and fix your bugs at the same time. Going from 120mbit to 720mbit in straight bridging tests is pretty amazing. I'll go see what I can find out about the forwarding performance. Hopefully there are some more low hanging fruit that I can address to increase performance a bit. -adrian
