Are you sure the problem is that you are CPU bound? Could this be a
memory or disk i/o issue?

[Please don't top-post; see the Guidelines]

Have you enabled multiple cores in your VBox configuration, as per the
manual?

On the "Processor" tab, you can set how many virtual CPU cores
the guest operating systems should see. Starting with version
3.0, VirtualBox supports symmetrical multiprocessing (SMP) and
can present up to 32 virtual CPU cores to each virtual machine.

You should not, however, configure virtual machines to use more
CPU cores than you have available physically.
