I have compared the performance of both XFS and Ext4. And since I use those big machines for backups, for me the write performance was very important. XFS was almost twice slower.
But lets leave XFS alone :) Ext4 is the way to go :)

I am using XFS on an HPC cluster, one single partition of 14 TB, with no problem so far.
See this news on Phoronix. XFS is becoming cleaner and leaner. I am happy to use ext4 instead of ext3 on usual partitions, but XFS on big partitions seems to me still a good choice. Let's see what happens in the future. http://www.phoronix.com/scan.php?page=news_item&px=OTU4OA

Btrfs happens in the future. :-)
