Hello demoralizer and welcome to PerlMonks. May I ask you to post some (working) code here? Just put what you already came up with, even if it is slow, at least we will get a better idea of the context, then we can figure a way to optimize it. Thanks!

There are no stupid questions, but there are a lot of inquisitive idiots.
