My point is that not a single shred of evidence shows improved performance on any youtube video when people made comparisons. It all showed the opposite.
What proof does anyone have of what the majority think of performance anyway?
Whats to say that iOS 9 improved some people's iOS 8 installs making it faster for them, accounting for some people finding it faster? That doesn't mean the system is faster, as the only real judge of how fast an OS is, is if you remove as many variables as possible (clean install) and compare.
I'm perfectly happy to accept that for whatever stupid reason, different devices (on clean installs) perform differently with iOS 9, but there is no evidence anywhere so far to show that. Show me some and I will believe
Why should iOS 9 be slower on 3 of my devices when its advertised differently? I don't get it. I've tried every permutation of ota updates, clean installs, settings resets etc and my second iPad 2, iPad Mini 2 and iPhone 5 are all slower in terms of app opening time, scrolling, rendering animations, turning on and application responsiveness. I've tested empirically and that also shows slower performance.
Give me some empirical data of iOS 9 being faster than iOS 8 on any device, using a clean install of both and then I'll believe.
