Well, I based my argument from the 10 instances of reverse proxies I'm running. It has 266,268,230 objects and 3.7 TB of space. CPU usage is always around 0.2 according to ganglia. So unless you have some other statistics to prove CPU is that important, I'm stick w/ my argument that disk

The cpu doesn't do any IO, it's WAITING for the disk most of the time. If you want fast squid performance, CPU speed/count is irrelevant; get more disks and ram. When I mean more disk, I mean more spindles. eg: 2x 100GB will is better than a 200GB disk. well well, get prepared ... take
