FWIW I would definitively like to see it. But thanks for going so far..
I will give it another try tomorrow as I dont have much time today.
However, I did one test with a new CPU. I changed the cpu from an AMD
3800 to an AMD4600. So going from a CPU with a clock speed of 2Ghz to
2.4Gz. The difference is sort of what one would expect. In the ipfw
tests, (with a sample of 40 seconds) opposite path forwarding with 10
ipfw rules went from 208 Kpps to 235 Kpps or about a 10% increase as
opposed to the ~ 15% increase in clock speed. Perhaps bus is more of
a limiting factor that CPU but then again some the difference could
be explained with normal variance.
