You are definitely right, I did mess up while translating !

I run the corrected codes (the ones I was meant to provide :S) and on a slow macbook I end up with :
C : 2
D : 15994

Of course when run on very high end machines, this diff is almost non existent but we want to run on very low powered hardware.

Ok, even with a longer code, there will always be a launch penalty for d. So I cannot use it for very high performance loops.

Shame for us..

Thanks and bye

This to me pretty much confirms that almost the entirety of your C code is being optimized out and thus not actually executing.
