I believe that you are looking at wasm with a different priorities than intended. The two fundamental properties are that it must be fully portable and fully secure by default (as in any insecurity needs to be explicitly and statically declared in the bytecode).

Performance comes only after those two. LLVM as far as I know, has a completely different order of priorities.

Personally I don't see why we cannot get all three.
