  Why make the assumption that performant software and functional software are somehow on the opposite side of the spectrum of what's possible? The point of the article is that performance is just as important to consider in addition to functionality and correctness. To use an analogy, it's easier to make a house energy efficient if its considered from the beginning, than if it's tacked on afterwards. In fact, tacking it on afterwards is sometime impossible without a complete renovation (analogous to re-writing the software).
