And here is the one for ReiserFS - same kernel, but recompiled to turn
off debugging

When compared to the earlier ones (including XFS), you'll note that ReiserFS
performance is rather poor in some of the tests  - it takes 37 vs. 13
seconds for 8192 inserts, when the inserts are different transactions.
