Indeed. Devel::DProf is good stuff. I was very happy with my results when using it and Benchmark to, erm, profile and benchmark my code.
As for Memoize, Limbic~Region's reply is correct. It won't really work for me in this case, because I willshould never have the case where my subroutine gets called twice with the same arguments (unless of course there's something wrong in my log and I get duplicate entries). Thanks for mentioning this though, I've been meaning to look at it for a good while now.
