;) No, I mean *relative* percentages: setlocal in your profile is on top, higher
than __convert_from_v and everything else. I'm asking: is consuming 1%, 10%, or
99% of the total runtime?

In this case, can you possibly check whether, for some reason, snprintf is
slower than sprintf, on AIX?

Thanks
