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? > Jeremy M.
