Q. How can I max out the CPU on my Linux box (for testing)?
A. Here are some good ways:
cat /dev/zero >/dev/null
cat /dev/urandom >/dev/null
grep hello /dev/urandom
None of these need any disk access so just take as much CPU as they can get.
On my box about 50%. If you are using these for purposes other than
stress testing your own box... you didn't hear it here.
