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
