Oooh, I hit a subject close to the heart of one of the developers! :)

I installed the centosplus kernel so I could play with JFS and ReiserFS as 
well as XFS. However, I don't think the XFS modules are present in the 
centosplus kernel package. At least I didn't find them under /lib/modules 
until after installing the separate kernel-module-xfs packages.

Already running x86_64 -- this host has dual Xeon 5130s.

So here's the big question, what are the pluses and minuses of XFS vs JFS vs 
ReiserFS? Below are some quick benchmarks. XFS clearly wins the speed contest 
unless there's some tuning that can be done. Any thoughts?
