XFS is slower than ext4 on certain metadata-heavy workloads, and faster in
multiple-stream workloads. It also scales better than ext4 on very big
filesystems. It is, however, more memory-hungry.
I use it extensively wherever I don't expect more than one crash an year.
Otherwise, I go with ext4 (better fsck).
