"Optimize" is a loaded term. I don't know of any methods to optimize,
though I know a few tricks to make java (and Tomcat) run faster.
First, run java in its own storage pool. There's a couple ways to do
this. I create a separate subsystem and allocate a pool to it. I
allocate either a private pool or one of the *SHRPOOLxx's. . . .
The J9 jvm's beat hell of the classic except in rare circumstances.
On older versions of the OS, that's usually what's known as the "32
bit" jvm. On newer systems, there's 64-bit versions of some J9's
depending on Java version.
