There's at least another 1000% to squeeze out by using more lines of code at the compiler side. Look at the wasm movement that wants to bring highly optimized intransparent code blobs to the client side and web servers written in rust so they can deliver even more complex applications in this post-moore world. Of course they'll sacrifice debuggability in addition to accessibility on that altar.

The problem the article reported is almost entirely about network requests, though. Relative to the speed the data was coming in, they had CPU and GPU coming out the ears. Switching the JS to WASM won't make that world particularly worse, nor better. It's the stuff generating fresh network requests that needs to change, and the size of the responses.
