We already have things like io_uring to achieve this speedup. As usual, this benchmark is comparing against an extremely naive implementation. It even uses a non-optimizing compiler! A fair benchmark would take advantage of all the features that native code has available - huge pages, CPU acceleration, io_uring, and, most obviously, a compiler that supports -O2. If they did that, the native code would smoke wasm.
