many prefabs. application Performance

Hi, I am developing for mobile.
I have a question.
If I have about 200 prefabs in my assets folder, and in every scene there are 10 prefabs.
In the performance of my application? 200 prefabs influence even if not loaded in the scene?

thanks

Only those prefabs are loaded into memory that are referenced in the current scene. Also if prefabs are not used anywhere in any scene in your build, they will not be included in the build.
