Asynchronous I/O and AIX and jfs = perf ?

To increase performance of oracle database 7.3.x.x, is it better to use Asynchronous I/O on AIX 4.3.x whith jfs file systems or not ?

I read in a redbook (Database Performance on AIX in DB2 UDB ans Oracle Environnements "SG24-551-00") it's a good thing.

But oracle tell if you don't use raw device is not good idea.

Where is the truth ?

Thanks
