> 4-5x slower than state of the art wasm JIT engines Does that mean browser engines?
- emteycz 6y ago
  I believe V8 is state of the art, with Gecko and then Cranelift behind it.

    I understand that Firefox is on average faster than Chrome at WASM, though there are plenty of tests where either is faster than the other. However, I can’t find much actual qualitative performance comparison of Firefox (there’s a little more of V8). A couple that I have found are https://www.usenix.org/conference/atc19/presentation/jangda https://www.usenix.org/conference/atc19/presentation/jangda (from almost two years ago), showing Firefox being about 20% faster than Chrome: > Across the SPEC CPU suite of benchmarks, we find a substantial performance gap: applications compiled to WebAssembly run slower by an average of 45% (Firefox) to 55% (Chrome), with peak slowdowns of 2.08× (Firefox) and 2.5× (Chrome). And https://github.com/wasm3/wasm3/blob/master/docs/Performance.md https://github.com/wasm3/wasm3/blob/master/docs/Performance.... of CoreMark 1.0 (higher is better), showing Firefox being about 5% faster than Chromium: Webassembly.sh (Chromium 78) 6914.325225 4.2x Webassembly.sh (Firefox 70) 7251.153593 4.5x

    wasm3 is slow for a reason actually. Its meant for IoT devices rather than full fledged PCs
- amelius 6y ago
  If it's slower, then perhaps it's more secure? (I.e., less optimizations that can have bugs)
  - ghusbands 6y ago
    If it's slow due to being simpler, that simplicity will probably lead to fewer bugs, indeed. If it's slow for other reasons, there'd be no clear correlation.

I think the emphasis is on cosmopoliton here. It's a cross platform c runtime + a cross platform exe format == cross platform binaries.

  Neither link mentions / links that. Do you mean https://justine.lol/cosmopolitan/index.html https://justine.lol/cosmopolitan/index.html ?

    The first page has a link to download wasm3-cosmopolitan.com.
