      The $349 iPhone SE is TWICE AS FAST as a $900 Samsung S8. That’s just not right regardless of how you slice it.

      Twice as fast according to a benchmark you happen to be fixated on. I share your goal but this tactic makes it worse

      Is there something you don't like about the benchmark? Or the fixation, just?

      Focusing on a single benchmark rarely results in better real world perf. Especially a microbenchmark.

      If difference is 50%, I buy that. But it’s a 500% difference. Even if it overstates real world by 2x, iPhone still more than twice as fast.

      If 5x diff in a benchmark doesn’t give us *any* information, then literally all benchmarks should just be disbanded. What can they tell us?

      1. Read http://benediktmeurer.de/2016/12/16/the-truth-about-traditional-javascript-benchmarks/ … 2. It legitimately doesn't tell us anything 3. Microbenchmarks should be disbanded

      Props for being logically consistent! Thanks, I’ll check out the link. That said, I’m curious, do you agree JS *feels* slower on Android?

      Yep. I'm just not sure what exactly is to blame. Hardware? JIT gaps? Memory pressure differences? All of the above at various points.

      Agree all those factors come into play, but would not underestimate Apple’s silicon advantage. I feel the diff as native mobile dev as well.

      5x? Or more like 2x?

          Depends hugely on what we’re talking about

          Bigly. Basically 2x seems like an accurate assessment of the hardware gap in general.
