Hi,
Is there significant performance drawback when using Sys.command to call
an executable compiled from ocaml code compared to calling the same code
from a .cmo ?

I haven't measured it, but I'd expect it to be insignificant compared
to the cost of the fork, exec of sh, sh command-line parsing, and
subsequent exec of your actual command.
