I'm still benchmarking it, against 2.6.26, 2.6.26-rc8-mm1 and
2.6.26-rc8-mm1 with the "evict cache first" patch.
So far the results look promising. I hope to publish the
benchmark results later today, when I have a full set of
all tests against all these kernels.
I have been running tests for about a week now.
