The way I often hear it expressed has nothing to do with small efficiency changes or benchmarking and it’s more of a yagni/anticipating hyper scale issue. For example, adding some complexity to your code so it can efficiently handle a million users when you’re just fine writing the simple to read and write version for hat isn’t optimal but will work just fine for the twenty users you actually have.
