And it might even be easy to use starting with the 2.6 kernel.

It was the fastest when deleting small files (and XFS was the worst).
I was surprised with Reiser's poor performance in other small file
categories.   I was also surprised that JFS did so bad overall.
I never used JFS, but I would have thought it'd be up there with XFS,
since they both came from proprietary software roots.  Not to mention
which company JFS came from ... I would have expected better.

That would be an interesting test.
