Object's timescale to 0 while offscreen improve performance?

I was wondering if setting an off-screen object's timescale to 0 improve CPU performance of game or automatically disables movement, platform or sine behaviors of objects? I was wondering if it was as efficient as disabling objects behavior while offscreen or even better than disabling them using the enabled = false event? I really want to make sure I am on the right track before I proceed. Thanks to those who will reply an answer especially Ashley XD

Answer your own performance questions with measurements

I would guess that you will not be able to measure a difference either way.

Thanks a lot XD
