Really. Are you on a particularly challenged connection? I just tried exactly that test and could barely get anything typed at all before the page display was finished. And it certainly didn't miss any characters. Obviously there is a lot more content on the page now than there was a few years ago, but AFAICT they've hidden it exceedingly well.
Honestly, the above seems like pretty bald hyperbole to me.
