Oracle says that ext2 and ext3 perform similarly, and at high
workloads OCFS or raw device access are preferred for
performance.

Since I value stability and fast recovery time for my
applications, we use ext3 on mirrored 3Ware RAID. Performance
has never been a factor, except when Oracle decided on a poor
optimization strategy. (Cured by supplying the appropriate
hints.)
