I’ve had some success with Mutagen’s [0] Docker support. Essentially you can set up a tiny Alpine container or similar with a volume mounted to it. Mutagen will then keep your code in sync using rsync, allowing you to mount that volume in other containers and bypass the performance hit.

It’s a bit of a pain to set up, and you lose some of the advantages of using Docker in the first place, but if you absolutely have to use it, it can get you back to full performance.
