And applying this thinking everything means that your entire code is pervaded with slowness with no obvious hot spots, and you jump with joy since it obviously means that your code is as efficient as it possibly could be (because otherwise the profiler will show some peaks, right?).
I know this was meant as (light) sarcasm, but have you ever profiled a nontrivial program that turned out to have zero peaks? My gut tells me this would be really difficult to do by accident. The same way that writing crypto code that is resistant to timing attacks is hard.
