aspnetcore/benchmarks/Kestrel.Performance

Compile the solution in Release mode (so Kestrel is available in release)

build /t:compile /p:Configuration=Release

To run a specific benchmark add it as parameter

dotnet run -f netcoreapp2.0 -c Release RequestParsing

To run all use All as parameter

dotnet run -f netcoreapp2.0 -c Release All
