Quick question.  I've been reading this as well as past threads and
understand the merit and functionality of the new SMP model.  However, how
much (if any) will Performance on both single and multi cpu machines
improve after this change??  Will the new systme use up more resources(ie
memory, swap, cpu) in single and multi CPU configurations??  I apologize
if this has already been brought up.
