I had to run it to believe, I confirm it's 183 seconds(!) for python3 on my laptop

Also, OCaml because I was interested (milliseconds):

    ocaml(int,noalloc,native) = 2022
    ocaml(int,alloc,native) = 2344
    ocaml(int,untagged,native) = 1912
    ocaml(int32,noalloc,native) = 1049
    ocaml(int32,alloc,native) = 1556
    ocaml(int32,boxed,native) = 7544
