I'd bet, with a high degree of confidence, that if you tried doing an IP

I used the DIY perf PIT, and my observations are that there is a lot of
noise in their test runs due to small sample sizes.
Another way to test would be to try doing performance runs with a 10g
card using something _other_ than TCP (UDP rx would be good). Look at
the improvements to the packets-per-second count rather than the thruput
numbers. :-)
If you're not CPU bound, you won't see the benefit.
Right. I wanted to run sanity tests to verify that I had not made things
worse. Performance improvement was not a primary goal, so I did not
spend many resources evaluating potential positive performance impact.
