Re: Fast of program

Before optimizing, it is recommended to run a profiler to see where the code is spending the most time.
Here is a good perl profiler: https://metacpan.org/pod/Devel::NYTProf

There are many tricks to make code faster, here are some that I often use:

- caching results of slow calculations
- keeping track of states with bit manipulation (like enums)
- using alias/references to avoid copying variables when not needed

Here is a video of various small tricks in perl to make code run faster: https://www.youtube.com/watch?v=jV5Zv3zc3o8
It is difficult to advise without seeing the code, you could post the code to https://perlmonks.org/ to get some good feedback :)
