Did a similar test in plain C: https://godbolt.org/z/ffYcWhxz3
It's not quite the same: I've used an increment instead of zeroing, otherwise the entire benchmark gets optimized away. Still got just about the same result (3.7x speedup for 100 iterations), so wasm did good there. Actually, now that I think of it, SIMD code performance probably depends on good register allocation more than on any optimization. |
