You would have to compare things like two functions which performed the same operation, or two equivalent for loops, etc. It's likely that OCaml must generate a bit more machine code, because (a) it has to add various run-time bounds checks, and (b) it has to do more bit shifts and boxing because of the representation of OCaml values. (2) How much less code do you have to write in OCaml because it has efficiency features like polymorphism, garbage collection, data structure matching and so on. These features means you have to write, & hence compile, less code overall. I would suggest that (2) outweighs (1), but I've not measured it.
