I'm making a mod that needs large number of entity prototype, around several hundreds in number, mostly as a hidden entity that replicate the behaviour that I want. How does these prototypes affect performance in any way provided that all of them only use core/graphic/empty.png (a 1x1 empty graphic).

They shouldn't effect performance in any measurable way.

If they do, then something is fishy and I'd look into it.
