+1 for \shell command itself, but does the performance fit for your purpose?
Spawning a new process is not so cheap, no?
-1 for -P option because it is too narrow purpose and 'ls' and '/tmp/'
is not portable. We don't need to include your workload because you can
use -f FILENAME to run your benchmark script.
