You'll need to post info on your "extract info" routine? This is probably what may be slowing up your code. I've worked with extrememly large datasets before(nearly 2G of data) and my programs have typically run pretty quickly(<10 min), however I was performing very simple transforms on the data. Are you storing things in variables? Using regexes? We'll need the details to help you.
