Possible explanation for jank in Android as opposed to iOS (20 millisecond core ramp on ARM/Android vs 50 microseconds on Apple/iOS)

Attached: 1 image Wait, 20 *milliseconds*? Either their kernel scheduler config is completely out of whack, or ARM/Qualcomm really screwed this one up. Apple cores can boost to max in around 50 *micro* seconds. 20 milliseconds is just broken. That's more than one frame, and that's how you get janky UI response and dropped frames. I hope this was a config issue and these cores/designs really don't take 20ms to increase clocks (I could see that with a really bad regulator/power delivery system...)
