Summary:
I have noticed that sometimes Xcode will perform poorly when opening a Storyboard or moving a number of elements from a ViewController (inside of a storyboard) from one view to another. This slowdown can also appear when zooming in and out in the storyboard. The beach ball will appear for a few minutes. Sometimes, this will cause XCode to crash, sometimes Xcode will just be unresponsive for a few minutes. 

My Storyboard is currently referencing 12 ViewControllers, which doesn't seem like a lot to me. The general flow is a UITabBarController which has a few modal views and 5 UINavigationControllers (one for each tab) spawning from the UITabBarController.

Steps to Reproduce:

Expected Results:
Xcode should be able to handle working with Storyboards. 

Actual Results:
Sometimes can be very slow. 

Regression:

Notes:
I am using Xcode 4.2 on Snow Leopard (because my company won't allow me to upgrade).
