The iOS 11 GM has been running smoothly on my iPhone SE and 12.9" iPad Pro, but I cannot recommend installing it on the iPad Mini 4 because it is currently stuttery and gross (even with a clean install). I'm crossing my fingers that Apple will optimize for it in a future point release because this device is barely two years old and still being sold by Apple. (Why Apple didn't see fit to put the A8X in the Mini is beyond me. Is it doomed to be the new iPad 3?)
I didn't find the right solution from the Internet.
