I was having a discussion with a coworker around sharepoints navigation, and was asked at what point does performance start taking a hit due to a large nav. (Correct me if I'm wrong) but I know that SharePoint renders the navigation dynamically. So
is it fair to say that if a site collection's global navigation has, say, 4 levels of flyouts, and tons of menu items that the site collection will in fact take a noticeable performance hit? Ignoring web design best practices where you wouldn't actually want
your navigation to fly out 4 times...
Is there any sort of documentation or facts from MS regarding this sort of stuff? For example, although technically possible, only allow 3 flyouts and up to 'X' amount of menu items?
