And I can tell you why. Commerce also instantiates the basket on every 
call, and the basket might contain basket_items which themselfs 
instantiate the article they stand for inside of them. So you might have 
more calls then expected. It also took a while for me to understand 
that, when I tried to speed up commerce a bit.
