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.
