Somehow, there is an exact 2s delay from nameserver resolution to connection setup #78

Describe the bug I've been experimenting with a local grpc server when I saw that each call needs exactly around 2 seconds. Between "resolution stop" and "connection established" there is a 2s delay for no reason. When I tried the same call in Insomnia gRPC, it was nearly instant.

To Reproduce Steps to reproduce the behavior:

  1. Have a grpc server
  2. Create a call
  3. Send call :)

Expected behavior That it should be blazingly fast

I cannot reproduce this: grafik

Could you try calling your API via http://127.0.0.1:8080 and http://[::1]:8080? I suspect IPv6 issues when resolving localhost, where Kreya tries to connect to the "IPv6 IP", but has to fall back to the "IPv4 IP".

Huhu :)

Yep, when I use 127.0.0.1 it is blazingly fast.

Ok, then that's the workaround for now...

As for improving this, we are blocked until https://github.com/dotnet/runtime/issues/26177 has been implemented into the .NET "gRPC infrastructure" (mainly HttpClient/SocketsHttpHandler).
