$this->read(1) triggers identity map of Doctrine (and others?) #7
Description
The read scenario always gets entity by id 1, which leads to triggering identity map, and these fast results compared to phalcon:
root@82c267f32816:/app# php run doctrine read 1000

I would assume other ORMs also have identity maps, not mamking the query another time, which makes the read benchmarks not comparable.
It can't be changed to $i+1 though, because only id 1 has the fixture data with the comments available.
IN addition compared to my numbers, your seems way too extreme. Why kind of base system do you have for docker? I honestly wouldnt trust any numbers coming out of a docker dev environment.
