I'd say in general that principle holds: this is the age of huge distributed computation systems, the most you can pay for a single core before it tops out is in the hundreds of dollars, not in the millions like it used to be. The high end isn't very high up, and we scale by adding boxes and cores, not by getting single CPUs that are unusually fast. Taking the other way of looking at it, from what I understand, CDN boxes are about I/O and not CPU, though I could be wrong. I can ask some of the Netflix people, a former report of mine is one of the people behind their front end cache boxes and we keep in touch. Perry -- Perry E. Metzger perry@piermont.com
