I've been using perl for a while now and I want to get into using the best methods to do certain things (or better known as getting the most of the available memory). I have a few basic memory questions and was wondering if anyone could help me so I can grow into a more efficient programmer.

Is tying over 5 hashes on a single page considered a waste of memory? If I try to tye..20 databases at a time would that, generally speaking, have a big increase on load time?

Would it use a lot of memory if I used an automated script to parse the text of a url every 5 minutes?

Is it faster to do a foreach ( keys %hash) { $cnt++ or storing the hash into an array to count key/value pairs?

What are some common areas or traps that would increase memory wastage?

I appreciate any information you have on memory or speed efficiency that you could spare. Thanks for your help.
