We've actually gone the other way, but for different reasons. We use XFS
widely now, due to the 16 TB limit on ext4. Performance tests on both
have come out reasonably similar, and we've not had any issues with XFS
(touch wood!). We also use the concurrency patch for dirvish-runall
(and a similar one for cleaning up expired vaults).
