Ah! I think I have the solution to the poor showing for the Sun SDK 1.3
I ran into this same doing my own tests with Synchronization & object
creation/GC on Linux, Solaris using Sun + IBM JDKs.
Sun decided to ship their SDK with the JIT defaulted to "client" mode rather
than "server". If I were to say "server" is provides a dramatic speed
boost, I'd be understating the situation.
Put a "-server" in the command line for running tomcat when using the sun
jdk. This should be on by default IMHO, unfortunately other VM's complain
about this. Requiring a bit of fancy work to eval the JDK you're running
on. For now, just hand hack it in there and run the Sun tests again! :)
I believe you will see the SDK perform at nearly that of IBM when you do.
(My own tests show IBM is still a more efficient at object creation that
sun, but the margin narrows considerably)
