No, I cannot, but you can ask the OC4MC team for numbers, to compare the
performance of their implementation with the official one for sequential
programs (coq, ocamlopt, etc.) I could only find 3 programs on their
slides, not really representative of classical OCaml programs, but one
of them already showed a 17% slowdown compared to OCaml.
