Looking for the comparison between these two webservers (https://caddyserver.com/ , https://github.com/containous/traefik/ ) both are written in golang, please share your experience if you are using any of them.

I am looking for following parameters

- performance in terms of memory usage and requests/second.

- ease of use, how much or little configuration is required.

- licensing issues if any.

- extra features gzip/auth etc.

- embeddability i.e using them as library in bigger webapp.(caddy clearly has the support not sure about traefik)
