It looks like early phase exploration on the one hand, but on the other hand Red Hat Beta 7 is already using XFS as the default filesystem:

Interesting. It makes sense to use XFS if you are dealing with high volume data.
That matches my understanding. For example, the MythTV project recommends using XFS for its video files. In particular, its performance when deleting multi-GB files is much better than ext4. With the latter, they have to throttle back the delete so as not to consume all of the CPU. I have a couple of kernel sources on XFS volumes, and the kernel builds sometimes pause. I suspect that XFS is not so good with small files.
I see the same, 13.1 + XFS is very good for file-sizes above 10MB, a few smaller ones do not hurt much, but XFS for rootfs (/)? - No, not ideal.
I did not have the time to test for file-sizes between 500 kB and 10 MB.
For me the best ever fs for small files and may directories (e.g. mail/news/static file servers[ftp/http]) in matters of speed (access+create+remove+change) and space-efficiency was and still is reiserfs (3.6), but btrfs still gets better, so we will see.
Apropos filesystems in general and xfs specifically: xfs is the recommended filesystem for data partitions in SUSE Linux Enterprise for some years already. xfs also will remain the recommended filesystem for data partitions in the upcoming SUSE Linux Enterprise 12, if not users demand snapshotting, and thus will chose btrfs. As you know, I assume, SUSE Linux Enterprise 12 will have btrfs as the default for "/", to enable snapshot/rollback right away. Yet if a separate "/home" is configured in the YaST partitioner, it will default to xfs. -- This way we closely follow our own recommendation, don't we? so long - MgE P.S.: I personally use btrfs for "/" and "/home", and xfs for the backup storage, ... just in case you were interested. -- Matthias G.
