Re: slow load and typecheck

I already mentioned needing .hi (I may have said hsc, whoops; Haskell Interface files) from dependencies; you really want to turn that part on, at least. And possibly ensure your other options are compatible with existing .hi files, so they can be loaded directly. I think the .o isn't used until link time, which should be irrelevant for you; but you really do want those .hi files, otherwise it must compile the dependency module to generate one.

Are you writing interface files (-fwrite-interface)? It makes no sense for HscInterpreted to be faster than HscNothing.

Nope, not writing anything like that (I just checked the ghc flags from hie-bios to confirm)... and I agree that this makes no sense.
