The delay is mainly due to way the panel captures the background image to apply the image blur in advance. It does this exactly once, when the gesture is triggered or when opened programatically, and then crops the image using UIView content modes, to show only the relevant parts obscured by the panel.

If you are using iOS 7, it's possible to get faster performance using some of the more "hack"-ish techniques (like stealing the CALayer of a UIToolbar), however, you lose the ability to specify the strength of the blur (required to match the look of notification or control center.)
