The number I find interesting is the better performance of 2.4 kernels.
The performance of the load generating programs is much better with 2.6,
but that's not what is of interest in this particular test.

I did one set of tests with the elevator options, I hope to do swappiness
next week. I'm trying to keep all the tests on the same machine so I can
compare old results.
