For our purposes we have historically used the Classic JVM, but we're
finding the 32-bit JVM to be quite advantageous for certain situations
where performance is needed.

We haven't done formal benchmarks, but it is much faster.

subject: 32 bit vs 64 bit Java

At V6R1 we have the following options for java (for the j9 versions)
5761JV1 8 J2SE 5.0 32 bit
5761JV1 9 J2SE 5.0 64 bit
5761JV1 11 Java SE 6 32 bit
5761JV1 12 Java SE 6 64 bit

Has anyone done any benchmarking, or has any experience or
recommendations on what is best to use? We currently support the
Classic JDK 5.0 and the J2SE 5.0 32 bit. I am wondering if there is an
advantage to the 64 bit versions.
