Description
Http.Sys has a feature for recording timestamps for major checkpoints in the lifecycle of a request. Partners like @bkatms use this to profile individual request latency issues. We've already exposed the Http.Sys data, but they want more checkpoints.
HttpSys:
- basline: https://github.com/dotnet/aspnetcore/issues/13482
- When dequeued from Http.Sys: https://github.com/dotnet/aspnetcore/blob/1d561c012913b7bb43bad4353722280e4c568053/src/Servers/HttpSys/src/AsyncAcceptContext.cs#L68
Kestrel:
- Reproduce as many of the checkpoints from Http.Sys as feasible.
IIS:
- Expose the native checkpoints https://github.com/dotnet/aspnetcore/issues/3842
HttpClient: https://github.com/dotnet/runtime/issues/827
