Try quickly typing 1+ 2 + 3 into the iOS 11 Calculator
As soon as I upgraded my 6s to 11, I saw performance seriously degrade. It takes -seconds- to bring up the iMessage editor.<p>My immediate thought was that Apple had liberally sprinkled wait() into the iOS 11 code base so that I'd feel like my ole A9 CPU just wasn't cutting it any more and I'd realize, as they do, it's time to upgrade.<p>Or... maybe they are running every key stroke through the new Azure-enabled Cray computers to better predict what I am going to type so that overall, my typing is more efficient and I'm actually spending <i>less</i> time typing...<p>Yeah. Yeah, that's it!
