You might remember my original GluserFS/OpenVZ benchmark which produced a horrible 29.8

This is the exact same system, but using the latest 2.0.8 (with some small files patch which speeds up performance) you can see it is about 25% faster.

I also haven't tuned my config files at all, but there are some settings that should increase performance on small files which I believe is the main cause of slow performance when running GlusterFS under OpenVZ
