I've only been able to test reiser4 on 2.6.2. I've been trying to track filesystem performance and have done it with 2.6.2, 2.6.1-mm2, 2.6.1, and 2.6.0-mm2, but I haven't been able to get results for every filesystem for one reason or another. Oh yeah, that ext2 4-way 2.6.1-mm2 result is way off. In most cases, I haven't tried repeating results. But other than weird cases like that, they usually don't vary so much. Mark
