Android vs iOS appium's execution speed, which platform support faster execution?

If we test the same kind of application on iOS and Android with appium, on which platform does appium perform execution faster and why?

For me I noticed that Android executes and runs through tests MUCH faster than iOS. To the point where I use Android when creating and making sure my testcases run through properly. I can probably run the same test on Android 3 times as fast as iOS, maybe faster. Why? I have no clue… Something I’d be interested in learning as well.
