You can improve this substantially on MacOS using docker-sync (the issues with Docker performance on Mac are primarily related to the file system)

I wrote a little about this; it's for Rails but the same ideas apply:

docker-sync helps a little bit, and so does limiting Docker to 1 CPU core, but I still routinely get spurts 100% CPU from Docker that despite supposedly being on 1 core still grind my machine to a halt.
