If it has been said once it has been said a thousand times "beware of premature optimization!" Ask yourself, "does this really need to be faster? Really?"

I think a very important item to optimize is code maintainabibilty - how easy is it to extend your program and fix bugs that break your code?

So, how do i optimize my Perl code? I generally don't (but i do try to get it right the first time - measure twice, cut once). If i do, it is to replace areas of wheel re-invention with CPAN modules, or to refactor items into classes to improve robustness. If i wanted faster code i would port it to C instead, but since most of what i write relies on database and web servers, Perl is 90% of the time not the bottleneck.
