As these results show, best results were from using a uni kernel, but an SMP kernel with "nosmp" was faster than running SMP. The problem is that with 2.5 kernels the SMP results for multiple runs vary by up to 2:1, and for uni kernels it's more like 5-10% max. I have tried longer runs, more runs, and gotten the same results even in single user mode.

Oops, a note of clarification on test names:
2.5.50 uni kernel
2.5.50smp smp kernel
2.5.50uni smp kernel with "nosmp"

Yes, I know that's not intuitive, but all my kernels are SMP, the uni tests are an afterthought...
