Did you notice the same time behavior for both ocamlc.opt and
ocamlopt.opt ? If yes, the problem comes during typing or
pattern-matching compilation. If no, it comes from native code
generation, probably register allocation (after inlining of small
functions, some functions can become huge, with many variables
interfering).
Benedikt Meurer submitted a linear scan allocator at some point, you
might want to try to compile your file with his compiler to see if it
goes faster.
