Multi-processor VM only uses ~50% of host CPU on dual core system

I'm running VirtualBox 3.0.8 on a MacBook (the original model) with an Intel Core Duo processor. I have a Windows guest VM setup with VT-x enabled and 2 CPU's. Looking at Windows' Device Manager shows that the guest is seeing two CPU's. However, when the guest is utilizing 100% of its CPU time, the host is only using approximately 50% of its CPU time, which would indicate to me that the VM is not utilizing both of the host's CPU's/cores.
