It was interesting to read about why hotspots are not the whole story in performance. They are still important though.
Facebook may have the resources and/or need to do complete rewrites of everything to squeeze out more performance, but most companies don't.
I've personally improved performance of a lot of code significantly by identifying hot spots. So calling hotspot performance engineering a fail seems a bit unnecessarily provocative.
