Can you at least explain a little more clearly what the subroutines are doing? "a couple called as command line arguments that simply print data to the screen and exit" doesn't tell me much. How long does it take to run? How much time do you want to trim?

If what you need to do is speed up specific subroutines, have you looked for any code that can be pulled out of sub? Are you opening/creating/etc some resource that could be held open to remove that step?

Optimization questions are pretty hard to deal with unless you have at least some idea of the problem.
