I'm not convinced that high traffic apps fair any better, except perhaps that user-facing loading requests are a smaller percentage of the total load. I've heard people with high-traffic apps on this list say "it's fine" but I've not heard any quantitative metrics like % of requests that go to cold starts.
In the absence of specific numbers to the contrary, I'm inclined to believe that high-traffic apps still dump an unacceptable number of requests on cold instances.
