Skin Responsiveness

So I am going to have a lot of animations in this skin I am working on…. May not be as light as I originally thought but will be worth it I believe…..But with that being said does Kodi respond better when using a lot of smaller .XML like several different types of includes….. Or would it run better with out any includes all code in bulk .XML but alot less.

My animations time range from 300 to 1000 so I want the animation to be seen and if Kodi lags it will be missed… So I just want to know if anyone has any insight on how the core respond s to the skin.
