"The tests performed by IOzone measure many things, starting with the simpler metrics such as read, write, reread, and rewrite performance. Read and write are obvious. Reread is measures how well a system caches a file that was recently read. There are two rewrite tests; the one reported as simply rewrite overwrites an existing file. The record rewrite writes to a specific location in a file over and over again. " http://www.linux.com/archive/feature/139744

Additions:
**In this test**, JFS & ReiserFS offer the best read performance, while XFS offers the best write performance. But that's just sequential read/write of a not-so-large file. I've had some good experience with Oracle on JFS and some bad ones with ReiserFS. ReiserFS4 and ext4 have promising performance but I'm too lazy to get my kernel to support them, and they may not be as matured as the others.
One also have to take into consideration about how often random access is used. Certainly not to under-estimate the effect that ext3 is officially supported and is widely used for obvious reasons. Think about when your fs crashes, you certainly don't want to learn that the fs is not supported by your favorate live-cd/rescue-cd.
