stress! Configured correctly it will abuse a server pretty hard

http://weather.ou.edu/~apw/projects/stress/
http://dag.wieers.com/rpm/packages/stress/

run like

cd /var/tmp
screen -dmS stress
screen -rx stress
stress --cpu 16 --io 8 --vm 12 --vm-bytes 512M --hdd 4 --hdd-bytes 1G --timeout 86400

Oh and be sure to set a timeout if you run it remotely or you'll lock
yourself out ;)
