Make sure you have guest additions installed into each of the guests.
Make sure you don't give all the CPU's to any single guest.  In my experience, I give each guest half the CPU's.  Then it load balances pretty well...  If I have 8 cores and I'm running 4-8 guests, I give them all 4 cores.  So I am overloading the CPU's, but as long as they're not all assigned to a single guest, they seem to load balance well.

Virtualbox disk performance is poor if you're using vdi.  (IMHO.)  So instead, wrap a raw device (zvol) in vmdk file.  It works much better.
