(I assume that's what you refer to?) It's a good measurement, but it's from 2019, and it's just on 2 wasm engines. There are other estimates, like here:

That tries to measure the fundamental overhead of wasm's sandboxing as opposed to a specific wasm VM, and it finds just 14%.
But e.g. sharp/vips ended up with a much worse result: https://www.libvips.org/2020/09/01/libvips-for-webassembly.h...
It may just be a matter of waiting for simd and threads though.
