This is a gross misrepresentation of the article. It is in your own head that he solely focuses on this one thing. When somebody says "this soup needs more salt" you start talking about how there always is too much salt in processed food these days? The article is a about a concrete narrow subject, not about "performance" (the entire field).
Can't some people read an article without extrapolating to the end of the known universe and just stick to just the article's actual narrow subject?
Take my criticism as being on the chosen title and framing.
It is a neat subject. Just as knowing different ways of measuring car utilization and power transfer. Framing it as a take down of how people commonly do it is extreme and at major risk of throwing out the baby with the bath water.
True, but useful? Most of us are busy trying to get writes across a networked service. Indeed, getting to 50% utilization is often a dangerous place.
For reference, running your car by focusing on rpm of the engine is silly. But, it is a very good proxy and even more silly to try and avoid it. Only if you are seriously instrumented is this a valid path. And getting that instrumented is not cheap or free.
