XFS is by far the best file system supported by Linux but only when it
works. For complex installations, like yours, XFS might not be the best
choice. I consider it under development where one version might work
while another might blow up the file system. But performance wise, on a
normal device, xfs is by far the fastest and much more compact. I know
that from my experience, df reported 6/20G used when using xfs, but
10/20G used when I just moved the file system to ext3.

The caveat is that xfs, between and for some kernel releases, is not yet
nearly as stable as ext3.
