Hi.
I've got two scripts I am running and they both consume large amounts

Both scripts start off with:
#!/usr/bin/perl
use warnings;
use strict;
use WWW::Mechanize;

hi,
you probably want to use s/// instead of tr///.
# perl -wle '$_=""; s//(\\d\\d\\d\\d)/; print'
(\d\d\d\d)
have a look at perldoc perlop to see what tr or y really does:
tr/SEARCHLIST/REPLACEMENTLIST/cds
y/SEARCHLIST/REPLACEMENTLIST/cds

Hi gurus,
