That is an insane difference even if nowhere close to native code.

Some engineering fields would be crazy with a 20% gain... 200% is huge!

I agree it still is signficant, but this is not how wasm is being touted. Look at wikipedia: https://en.wikipedia.org/wiki/WebAssembly#History

They even say asm.js is supposed to be "near-native code execution speeds". In my experience, it is no where close to native speed. People should avoid this kind of deceptive marketing.

On that front, I agree. Wasm is being sold as the greatest innovation ever, when it is just another virtual ISA with lacking features and performance.
