anonymous wrote : We could try affinitizing the JVM to certain CPUs. Would you be able to advise how this can be accomplished? While Windows gives you tools to change affinity (Task Manager), Linux typically does not (I say typically because I am not familiar with the tools Ubuntu provides, I tend to use Fedora Core and occasionally RHEL). You usually have to write your own code to set affinity. Google the Portable Linux Processor Affinity API.
