in thread Massive regexp search and replace
Well, all direct text translations might be handled faster... but unless there is a lot of them compared to others then it probably won't help (might actually be slower). The actual help would be better to be tested as this is pure speculation :).
Basicly make to hashes instead of one. Something like this.

Note that in the given examples, you might write out the '[Tt]ile' pattern to Tile and tile rows. Which would move it from slower pattern group to faster. But as I said, I'm not sure how much this would help.while (<REGEX>) { chomp; my ($key,$value) = split (\t,$_); $value = "\"$value\""; if ($key=~s/^\w+$/) { $simple{$key}=$value; } else { $regex{$key}=$value; } } while (<INPUT>) { s/$key/$regex{$key}/gee foreach my $key (keys %regex); foreach (split (/\s+/,$_)) { if (exists($simple{$_})) { push (@line,$simple{$_}); } else { push (@line,$_); } } print OUT "@line\n"; }
