I would guess Ocaml wins in performance. Shootout at alioth gives:
(CRAPS scores)
gcc -- 57
ocamlopt -- 40
ghc -- 18
ocamlbyte -- 15
python -- 16
felix -- 3.3 (ouch!)
curry (Haskell) -- 0.13
which seems to indicate, at least for statically
typed languages, that performance is most closely
related to the intensity of effort put into the
optimiser.
However, Haskell being purely functional may
make high performance data structures unavailable,
for example arrays (time in secs)
gcc -- 0.02
ocaml -- 0.04
ghc -- 1.4
