I am up for pushing it if you do not think it is a waste of time.  Based on 
what I am seeing it looks like I just need a faster CPU to do the work.  My 
goal would be to hit zero dropped packets w/ 10-15% CPU to spare but I fail 
to see how that will happen on this box.  Do you concur that it would be 
highly unlikely I would be able to get that kind of performance increase?
