Stress testing your machine -- what program?

[William Park]

When there is nothing going on, hdparm, dd, kernel compile, etc., gives
expected numbers.  When things are going on, however, my machine
crawls/freezes/stutters in a way that is not linear in terms of system
load.  I looked at swap, and it's not even using swap.

I found StressLinux from <distrowatch.com>... downloading...
