Docker performance issu

Xiaobai asks a question: on a server (such as 4core 16G), use docker to run a web application and launch only one container. I understand that docker is a process, so will there be any performance problems in the docker container? Can you make full use of the hardware of the server?

using docker is generally not as good as using a machine directly, which generally has little impact and is better than a virtual machine.

if you have extreme performance requirements and the machine is limited, you'd better not use it.
