🏁 Results

  • ~20% faster code
  • Gen 0 is only one third (-68%)
  • Gen 1 is only one fourth (-76%)
  • allocations have halved

ℹ Remarks

  • Performance has been greatly improved with .NET 9. The comparison between .NET 9 and HyperLinq with .NET 8 shows that the .NET 9 system is now faster.
  • The development of HyperLinq seems to be inactive and does not exist for .NET 9 so far.

⌨️ Run this sample

dotnet run -c Release --framework net9.0

Updates

  • 2023/11 - Add .NET 8
  • 2024/11 - Add .NET 9
