DB2 9 FP3 - Linux vs Windows engines with AIO or a Db2 universal jdbc driver performanc?

P: n/a
How can I be sure that DB2_LINUXAIO is working properly in DB 9 FP3?
The parameter db2_linuxaio was depreciated from the base version to
FP3 and my performance tests have shown a decrease in performance
between the versions.
DB2 9 FP3 on windows compared to windows seems to be about 40% faster
in my first test. I have a few more to run...

DB's are configured that same in Windows and Linux. My tests connect
via jdbc and use the Db2 Universal jdbc driver.

I have two theories, either the AIO isn't working correctly in Linux
FP3 or the jdbc driver doesn't perform as well against a Linux engine
compared to a windows engine.

Anybody have any information on either of these?
