taddison / metric-collection-benchmark

How fast (slow) is that metric collection?

Curious to know what overhead a TrackDependency call added. And then I also wondered if a stopwatch was faster/slower than comparing DateTimeOffsets. And now I know!

Build and run all benchmarks

dotnet run -c Release --filter * --join
