I dont think you should focus on performance. Is your data safe with XFS, ext4, etc? No. Read these PhD thesis and research papers:
XFS is not safe against data corruption:
http://pages.cs.wisc.edu/~vshree/xfs.pdf
And neither is ext3, JFS, ReiserFS, etc:

"I came across the fascinating PhD thesis of Vijayan Prabhakaran, IRON File Systems which analyzes how five commodity journaling file systems - NTFS, ext3, ReiserFS, JFS and XFS - handle storage problems.
In a nutshell he found that the all the file systems have
. . . failure policies that are often inconsistent, sometimes buggy, and generally inadequate in their ability to recover from partial disk failures. "
But ZFS successfully protects your data. Here is an research paper on this:
