I let it run for about 10 minutes just doing normal activity - but if I am not running the CPU hog it immediately jumps to around 8,000, versus about 500 with the cpu-hog. So that means whenever I am machining I would need a cpu hog running I guess? It is really counterintuitive! >> I would like to set the CPU as instructed, but I have never used grub >> before.

Too bad, it would have been a better solution than the cpu hog.
