You don't have to recompile for different architectures. Just compile once to wasm and it will run in all platforms it supports at the same speed. Note: the author mentions this too.

"WebAssembly’s 32-bit integer indexes break LLVM’s vectorization due to pointer aliasing. Once fixed-width SIMD instructions are added, native WebAssembly will close the gap entirely, because this vectorization analysis will have happened before the WebAssembly compilation step."
