use Disclaimer qw(optimization is probably a waste of your time);
If you're looking at the same string over and over again you could use the
study() function to optimise the regex searches.
Make sure you're using the right tool for the right job i.e use
index() instead of regex if you're just checking for sub strings within strings.
Try avoid using saw-ampersand (
$&) as it can slow down the execution of your code.
