I hear what you're saying, but my intuition disagrees with you. Asmjs was optimized in browsers when I did that test. I think people tend to overestimate how much subsequent versions of V8 improve performance in niche areas like TypedArrays. Especially now that V8 is very mature. I suspects if I re-ran that test, performance would have improved across the board but I'd get the same relative performance result with TypedArray code. It would be fascinating to try though. I wish I kept the code.
