While it's true that Squid itself is generally not CPU-bottlenecked the overall throughput can be hampered if you're running redirectors on a machine with insufficient CPU horsepower. I use the Adzapper redirector and the cumulative CPU time used by the redirector is 3 - 4 times that used by the Squid binary. (2.5S14, on a Linux system.) If you're going to be running porn filters or virus checkers you can expect that the CPU will play a role in overall Squid responsiveness.
