JFS performance is generally good, in fact it was the fastest of any for 
large big writes (writing many-gigabyte files sequentially).

However, under the bonnie++ mixed-bag performance tests, both locally 
and over NFS, the xfs performance stats were faster, though anecdotally 
seemed to consume more processor.

JFS, I believe, is also hands-down the fastest at deleting even an 
extremely large file.
