> “Near-Native Performance”: Wasm is often described as having “near-native performance”. What this actually means is that WebAssembly is almost always faster than JavaScript, especially for compute-intensive workloads, and averages between 1.45 and 1.55 times slower than native code, but results do vary by runtime.
Yeah, nah: https://github.com/zandaqo/iswasmfast
JS is about 10x faster than wasm in simple linear regression, and 30% faster in levenstein distance calculation.
