Leo, I know this is a Perl mailing list, and I'm a Perl guy myself, but I was dealing with the same problem a couple of months ago and actually found a much better solution not using Perl. I was trying to extract data from a set of CSV files of approximately 7MB each, one per day for the last 9 years, so several tens of gigabytes of data. Using Perl to do this took close to two hours, which was too long for what I wanted. I coded the same script up in Awk (actually gawk) and it runs through all the files in about five minutes. If you're doing a lot of extracting data from large text files like this, take the time to learn Awk. It's not hard, and it's both conceptually and practically ideal for that sort of task.
