I have an iPad 2 and I've noticed every time I receive a Banner style notification (the temporary pop in bar at the top of the screen) inside of a game app the game visibly stutters for half a second.

Is this just how banners always affect performance? If I disable banners for an app will that eliminate the speed hiccup or is this a problem with the behind-the-scenes notifications too?

This is the current state of iOS. You'll notice that incoming calls and pop ups (the old style notification) also negatively affect the performance of current app.

Is this a new issue in iOS or have past versions done this too? I'm wondering if they might fix it or if it's an "always been this way" sort of situation... –  Ben Brocka Jan 2 '12 at 21:41

@BenBrocka The new notification center is only there since iOS 5. With you, I do hope they will improve it in the future, but who's to say? –  Gerry Jan 2 '12 at 22:16
    
@BenBrocka as Gerry has said, the banner notifications were introduced in iOS 5, but I can assure you that calls and the previous notification pop ups (now called "Alerts") adversely affected the system even in prior iterations (iOS 3 and 4). It seems even the added horsepower of the A5 and 512 MB of RAM are not enough to offset those resource intensive operations. –  cksum Jan 2 '12 at 23:31
