Q.  How can I "peg" (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
tail /dev/zero
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.
