Ok, I think I've solved this problem. Corbin, you're right, the problem is too many subviews.
What I did to counter this problem is to actually draw most images/text in my prototype NSView subclass rather than using subviews like NSImageView and NSTextField. This yielded a pretty noticeable speed increase. Hope this helps anyone else having similar issues. Key point: just do the drawing yourself.
