Can you expand on that? In my experience nothing about Docker implies a performance impact in terms of size or start time.

Well, there is the overhead of creating and removing namespaces each time a container is ran, or communicating with the Docker daemon.

I think to most people it would be negligible, but fb operates at a scale where these normally insignificant pieces matter. I would be interested to hear more about the _why_ of a system like this over containerization.

edit: rwmj's comment has a good discussion over the benefits of this over containerization.

I promise you 100% the overhead is docker and nothing else.
