How can you make idle processors pick up java work?
~
While running top I noticed that most processors running the same executing
java instance are idle

I need to work on vast amounts of data.

Is there a way to make these processors pick up/share work also, or do you
have to use some sort of scheduling framework on top of java? ~

Use multiple threads?

I have to echo Joshua's comment. What are you doing now that you expect a JVM
to be executing more than one thread? The full protocol stack would be good to
know, as well as any frameworks you are currently using. Some are
multi-threaded, some aren't.

You need multiple threads. There is no way two processors can gang up to boost
the same thread.
