Not bad, but not that good, either. Try running xfs_fsr into a nightly
cronjob. By default, it will defrag mounted xfs filesystems for up to
2 hours. Typically this is enough to keep fragmentation well below 1%.
I ran it last night on the raid array, it got the fragmentation down
to 1.07%. Unfortunately that doesn't seemed to have helped.
