Those are results of running your example (with 1e8 iterations) on Windows and Linux, respectively. Looks to me, "C from C" on Windows got optimized away, but "C from Perl" gives same picture (lagging behind, W vs L) as in OP. And right now I'm interested in eliminating this lagging. Optimization to try to avoid 1e8 calls is in future plans ;).
