This repo contains three equivalent console apps targeting .NET 8, .NET 9, and .NET 10 to compare runtime performance on the same machine.

• Net8App/PerformanceTest - benchmark runner for .NET 8
• Net9App/PerformanceTest - benchmark runner for .NET 9
• Net10App/PerformanceTest - benchmark runner for .NET 10
• ResultsComparator - prints a side-by-side comparison (based on the latest run outputs)
• DotNet_Performance.md - writeup (Markdown)

• Windows / Linux / macOS
• .NET SDKs installed:
  • .NET 8 SDK
  • .NET 9 SDK
  • .NET 10 SDK

Verify:

dotnet --list-sdks

From repo root:

dotnet run -c Release --project Net8App/PerformanceTest/PerformanceTest.csproj
dotnet run -c Release --project Net9App/PerformanceTest/PerformanceTest.csproj
dotnet run -c Release --project Net10App/PerformanceTest/PerformanceTest.csproj

Each run prints a summary to console and also writes a JSON file into BenchmarkResults/.

dotnet run --project ResultsComparator/ResultsComparator.csproj

• Run in Release mode.
• Close heavy background apps.
• Run each benchmark multiple times and compare medians.
• Prefer running on the same power plan / CPU governor.
