I my particular configuration I have noticed improved performance with 
more CPUs, when a few interfaces were used concurrently.  I have used at 
most 3 click threads as I wanted the remaining CPU for my user 
application.  It appears that speed up can be achieved when the 
SaticThreadSched element is used; however, one must be careful when 
assigning elements to avoid cases where frequent cache misses occur.  I 
think it would be useful to be able to assign an entire path to one CPU 
to avoid caching issues.

something like this:
Poll0->DoSomething->ToDev0 CPU0
Poll1->DoSomething->ToDev1 CPU1
