Speaking about which, it would probably be good to adjust a little how the filesystem is created and mounted (both in xfs and ext3/4 cases). E.g. lazy-count=1 is still not the default last time I checked mkfs.xfs. And even ext4.txt from kernel documentation recommends mounting it with data=writeback,nobh when doing comparison with metadata journaling filesystems (the same would go for ext3).
Along with different journal sizes, keeping an eye on stripe & stripe-width, and other settings that might be of interest.
