The amount of delay is insignificant, but I know you're working on something that only the gods would consider a throwaway. I’m not sure it’s directly related to the size of the project, but it does seem related to the depth of the file shown in the assistant. It gets a lot worse when the navigation bar is too wide to fit and has to condense its cells; during the flicker I can see it drawing with first one cell expanded and then another.
I got a great sample where I was clicking once a second in the main editor, and poor Xcode was spending 50% of the time redrawing the window, most of that in -[IDEPathComponentCell drawInteriorWithFrame:inView:]. That’s an awe-inspiring amount of work for a 2.3GHz CPU to be doing ;-) I attached the sample to the bug report I filed, rdar://15407075.
