Hi Christoph,

We tested 2.6.24-rc5 + 76be895001f2b0bee42a7685e942d3e08d5dd46c

For 2.6.24-rc5 before that patch, slub had a performance penalty of
6.19%.  With the patch, slub's performance penalty was reduced to 4.38%.
This is great progress.  Can you think of anything else worth trying?

operating system, but compare it to ours.  We can't possibly take such
a retrograde step."
