Don't use print for this sort of thing; use a profiler (Devel::Profile, as davidrw mentioned). Profile your program with a relatively small load (i.e. have your program print a small fraction of the map, for example). That should be enough in most cases to tell you where the bottlenecks are, without having to wait for a long run to finish.
