A simpler one I've been using recently involves just dd, plus nice to ensure it gets as much CPU time as it can. > nice -n -20 dd if=/dev/zero of=/dev/null bs=1024k Pretty intensive...I guess if you wanted an even more intensive test, you could create a real-time scheduled program (sched_setscheduler(2)), but that could be a tad overkill ;-) Hi Derek, just came across your post searching for simple stress-testing techniques.

Pretty intensive…I guess if you wanted an even more intensive test, you could create a real-time scheduled program (sched_setscheduler(2)), but that could be a tad overkill ;-)
