Generally XFS and JFS are considered superior to ext2/3. ext3, in my experience, isn't much slower than ext2. Plus the decreased time required to bring up a server after a power outage is worth something too. Having used ext3 quite a bit, I'd say it's fairly stable and reliable, but I have seen references here to know, possibly unfixable bugs. I've used XFS a few years back, and there was no great gain for what we were doing at the time, as we were CPU, not I/O bound. ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
