Is the data in the file in some sort of structure by the time you get to the regex you're looking for? If so, maybe using <a href="http://search.cpan.org/~mjd/Tie-File-0.96/lib/Tie/File.pm">Tie::File</a> to skip however many records are before the regex. You can also go so many records from the last one in the file, without loading the whole file into memory. HTH
