BTW, if there is a problem with the current WASM performance, it's probably SIMD.
Again, based solely on my own benchmarks, exclusively in the area I'm interested in (game-type workload, so, say, multiplying many small matrices, performing geometric tests), there is little to no speed-up from wasm-simd128 (where it is supported), whereas native code compiled from the same sources, by the same compiler, profiled on the same machine, seems to be running a bit faster when vectorized.
