Optimizing existing Perl code (in practise)
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,
If i do, it is to replace areas of wheel re-invention with
CPAN modules, or to refactor items into classes to
