Benchmark performance comparaison for .net core in docker

I’m wondering the performance difference between running a .net core web application with kestrel in a docker container on linux ubuntu with Nginx web server as load balancer versus running .net core web application directly install on linux ubuntu and Nginx.

In sort, I want to know is there is a performance lost when running in a docker container and docker service.

The application is a web api application that make call to an MySql database hosted on another dedicated server.

OS Version/build : ubuntu 16.04
App version : .Net core 1.0

Thanks
