      Profiling OCaml is very easy. Just compile with -p, then run and collect
      profiling results using gprof:

      $ ocamlopt -p foo.ml -o foo
      $ ./foo
      $ gprof foo >profile.txt

      Right at the top of "profile.txt" will be the most time consuming function,
      which should be a huge help here!
