Never quite got this argument. You can frequently do 1000 fold improvements or do even better by optimizing within the same algorithmic complexity. That frequently flips the bit of "is this software usable". Sometimes you can even make real world performance significantly better by ignoring the technically better algorithmic complexity, especially when you almost always with low n's
