RE: raw vs cooked filesystem for Oracle

According to the below white paper, they were able to get near-raw performance on AIX with the Concurrent I/O option:

I've also had good/excellent performance with concurrent I/O, but never compared it to raw so I can't really say how the two would stack up.

I am writing a recommendation for one of my clients on using raw versus cooked filesystems for Oracle data files. Have you come across any recent documents regarding this topic?
