Are there major inefficiencies in Haskell compared to OCaml?
If so, can something be done about them?

There are definitely some gotchas when it comes to performance, mostly in the realm of inadvertent space leaks and such.
But that's just it, they are gotchas. A new haskeller will no doubt encounter them, but they are generally simple to fix.

When Haskell and Ocaml are coded by their respective experts, I would, in general, trust Haskell to be faster.
