I thought of a use for my old Pentium 2. I'm going to put it and FreeBSD up to the stress test. Remember that old programming challenge where we made factoring programs? Well my program can factor 100 quadrillion in about 2 minutes on that computer. So I decided to set a cron job to run that every 10 minutes. I want to keep the cpu usage kind of low so it doesn't burn up. It has a passive heatsink after all. I may raise it a little later but not much. Basically I want to see how long it can run with some stress on it. And I don't want something that uses the hard drive a lot. Any suggestions or comments to make this test better?
