You are right, I am sorry for this omission. Having done that, the
ration between Ocaml and ATS times drops to 3:1 (Ocaml being slower).

Yes, I think the ATS code does perform bound checking. There is
probably a way to avoid it but I do not know how to do it yet.
With "ocamlopt -unsafe", the ratio drops further to 2:1

No. Standard Intel x86.
