Where are the performance gains with iOS 9? I've finally gotten around to trying the beta out on my iPhone 6 and I don't see any speed difference. I then went back to apple website to re read what they say about iOS 9.
"The apps in iOS 9 now take advantage of Metal, making more efficient use of the CPU and GPU to deliver faster scrolling, smoother animation, and better overall performance. Email, messages, web pages, and PDFs render faster. And multitasking features on iPad feel fluid and natural"
Keeping my fingers crossed that final release will show some improvement in performance. We have a iPhone 5 in the household that is still running 7.1.2 that renders web pages faster in safari than this.
