I profiled my attempt, actually reading each line is the bottleneck.

  Perl is always going to be much faster than Java at tasks like this. Use stdin and chomp() instead of reading each line explicitly. This is really a small, trivial task for a perl script. Even with a billion lines this is nothing for a modern cpu and perl.
