The perlperf manual page has some advice.

In my opinion, the most important part is profile first, so that you know where the slow parts are. Devel::NYTProf is the best profiler I've ever used, and I can highly recommend it.

If your application is backed by a database, it might also worth investigating if indexes might be missing. Most database servers the capability to log slow queries, which you should use and act upon.
