You're citing a paper using, as an example, an already highly hand optimized and performance-guided optimized binary.
That's what you get after you profile and optimize.
Edited to add: Since apparently you also work at Google, you should walk over to Svilen's desk and just ask him if profiles of production software are generally flat, or if they generally have hot spots.
