I confirm those numbers, on my laptop I get 21/17/13.

That's a really good question actually! Even if you used hints to 
prevent caching from MySQL, you may try to move that into 3 different 
(sub-)methods and change the order to make sure one loop does not 
influence the other.

Interesting! Some investigation has to be done.
