NativeAOT defaults to x86-x64 (sans v2) unless specified otherwise. If we compare to C and C++ submissions, they mostly use -march=ivybridge with -O3 optimization level. In order to make such comparison fair, you could use the following build options in .NET: <OptimizationPreference>Speed</OptimizationPreference> <IlcInstructionSet>x86-x64-v2</IlcInstructionSet> // (or 'native', to match march=native) These can also be passed as arguments to `dotnet publish` if necessary.

  Done but just + - not a difference.

    Thanks a lot! Now the numbers are much more in line with what is expected from startup cost sensitive benchmarks: https://benchmarksgame-team.pages.debian.net/benchmarksgame/fastest/csharpcore-csharpaot.html https://benchmarksgame-team.pages.debian.net/benchmarksgame/... and supposedly certain AVX-dependent (AVX1 that is, the only kind supported by ivy bridge) implementations no longer fail. If only there was an option to add side-by-side arbitrary options (e.g. Go vs C# AOT), but I suppose that's what contributions are for :)

      4 broken programs are shown, if you can fix ‘em that’s what contributions are for :)

      I'll just show the measurements that are available and leave you to choose what to do with them. https://benchmarksgame-team.pages.debian.net/benchmarksgame/#measurements https://benchmarksgame-team.pages.debian.net/benchmarksgame/...
