2.4.23 looks good -- see below -- these are acceptable numbers for a 100M
network. I reran the 2.6.0-test6-mm4 benchmarks and it still is much slower than
the the 2.4.23.
Question for Jason: -- are you running the 4/4 vm layout in your kernel? My
2.6.0-test6-mm4 has the 4/4 vm enabled -- which can have an impact on
performance. I'll tetest with 2.6.0-test9 without the mm1 and 4/4 vm enabled.
