1. There's no real limit to how slow you can make code. So that means there can be surprising large speedups if you start from very slow code. 2. But, there is a real limit to the speed of a particular piece of code. You can try finding it with a roofline model, for example. This post didn't do that. So we don't know if 201ms is good for this benchmark. It could still be very slow.
