Hi sweatje,
Many thanks for your tests !
You pulled up the count to 34816 ! New best score ! Bravo !

In fact, as you could see, it's not the counting limiting but the sender
It's only test to ensure the counter will allways "follow"

You're right a production version should be optimized.
That with ugly is to forgot in fight against nanoseconds

Nevertheless the real sender code wich will be included in the script whose hits are to be counted *willl* keep the @. As side statitistic that should not block nor alter the production.
But it's a good idea for tests, just to pull up the stuff.
I don't know for opcode ? I tested under Apache 2.0 Filter without problem.

So, I can just say MERCI !
Next week with graphic output. You like that ?
