My question is, is this a known slow spot?
Yes.
I've never noticed NSNotificationCentre being so slow before, and can't think why it would be. And of course, what can I do to help it? I've temporarily removed the addObserver call in the code and sure enough it goes a lot faster. Trouble is, I do need that notification. Any ideas?
Don't add thousands of observers. Re-do your design so that one observer can process the thousands of objects that need processing instead.
