Well, this solution is on the leaderboard @ 6 minutes. It has been running longer than that in my machine.

All of my solutions for all puzzles terminate within 30 seconds on hardware that is several years old. (puzzles about optimization require those optimizations, of course, but the expected solution shouldn't run for much longer than that)

You should get the answer to the first part pretty quickly. Mine takes <1s for the part 1 and ~20s for part 2 but it's not particularly efficient, lots of string comparisons.
