I'm still learning to benchmark myself, and don't want to lead you astray, so the best I can do would be suggest the tutorial Benchmarking Your Code , and the sections related to benchmarking/the Benchmark module in Programming Perl and Mastering Algorithms with Perl (both published by O'Reilly) and David Cross's Data Munging with Perl (published by Manning).

Can some of the more knowledgable monks please suggest additional sources for information?
