I guess it really depends on your workload, your HW, kernel etc. >From my experience, having XFS with lazy-count=1 and kernels 2.6.31.X gives better performance in our HW RAID 10 + BBU servers. We do have this configuration in around 200 DBs without any stability issue. I still have pending to test ext4/xfs with 3.2.X kernels... Manuel.
