Problem in Factory logic in version 8 up

[ThunderBirdsX3]

I found this problem after upgrade my project from v7 to v8 then refactor factory and seeder class.
It not a bug, But i think this problem come from logic.

Because it try to call newInstance it mean new Class every single chain method call like state count etc. And I think that not good.
It should call something like setAttribute .

I got the problem because my Factory class, Have to query some data from database (Data from seeder, I use factory to generate mockup data, When init project for development), Then it very very slow, Because it call newInstance too much.
