Answer 1

e.g. run a profiler on a similar machine.

• try a newer version of Java 6 or 7. (It may not make a difference, in which case don't bother upgrading production)
• try Centos 6.x
• try not using VMware.
• try reducing the number of threads. You only have 8 cores.

You many find all or none of the above options make a difference, but you won't know until you have a system you can test on with a known/repeatable work load.
