I'm matching surfdata (i.e. url's) against a list of almost a thousand patterns in the first iteration.

The data looks something like:

1217930320 jydawg http://www.perlmonks.org/index.pl

and a relevant pattern might look something like:

*.perlmonks.org

With the large amount of patterns I wonder if I would benefit from Regexp::Assemble or Regexp::Trie.

I'm looking into the other 2 pieces of advise. I don't suppose sticking a Gigabite of text data in an array is a good idea :P. Well maybe in chunks ...
