I have been seeing a lot of talk about how to optimize docker image size. And while it’s true that a smaller image can be downloaded faster from the docker hub, I am more interested in the actual impact on performance of the image size on the local system. Does it actually make sense to make a image from scratch, or should one just use images like Debian?
So before I go off to testing, I was wondering if anyone has already done this? Is there any available data of image size impact on container performance?
To clarify a bit more, I am interested in the difference of the I/O, storage, RAM and processor use.
