Do Not Use Docker if You Need to Boost Speed. Docker containers are smaller and require fewer resources than a virtual machine with a server and a database. At the same time, Docker will use as much system resources as the host’s kernel scheduler will allow. You should not expect Docker to speed up an application in any way.How to check Docker version?
But probably a lot easier if you right click on the windows icon in the lower left corner, pick Apps and Features and click Docker Desktop in the list on the right hand side of the new window. You will see a version number like 188.8.131.52 or similar. This is the version of Docker Desktop.
