The difference is that it doesn't take 600ms for a Rust binary to render "Hello world!" to stdout. In the context of CLI apps, binary size is irrelevant to the functionality of the demo. In the context of web apps, bundle size and speed _does_ matter, so 108KiB and 600ms are very relevant data points. Besides, I'm pretty sure that in this framework's case the final bundle can also be trivially stripped, but would that also reduce the render time? It's difficult to tell, and maybe those things should be mentioned in the demo. (Sidenote: I haven't confirmed whether what 0des posted is true or not; I'm just going by the fact that you're defending it.)
