My experience troubleshooting I/O performance over iSCSI is that Ext4 journaling has a much higher CPU overhead than XFS does. Papers I've read show evidence that "modern" XFS journaling scales better (better performance) than Ext4 as disks grow larger. http://lwn.net/Articles/476263/
As a sysadmin, I like XFS management tools better than I do Ext4's.
