I guess traversing through directories may be faster with XFS, but in my experience ext4 perfoms better than XFS in regard to operations (cp, rm) on small files.

Well, it's the delayed allocation of XFS (which prevents fragmentation) that does not like sudden power losses :) But ext4 has that too, you can disable it though - that should be true for XFS too. But the power situation in the datacenter has never been a problem so far, and even if the cache partition get's screwed, we can always rebuild it. Takes a few hours, but it would not be the end of the world :)
Yes, XFS hates power failures. I got a giant UPS for my home desktop to use XFS because of it's excellent performance ;-)
