For affiliates with sites with high traffic, do you ever have to worry about CPU usage? Are there ways you can limit your CPU usage without hurting quality?

Cpulimit is an application for Linux that can limit the CPU usage of a process. It is useful if you want to restrict a particular application from taking up too much CPU resources and thereby crashing the system. This can also be useful when you need to run several intensive programs simultaneously.
