Docker for Mac has been plagued by chronic performance issues since it was released. Over the years, many attempts have been made at speeding things up. This was my second attempt at a performance boost, which eventually led to the inclusion of Mutagen-based functionality integrated directly into ddev. (My first attempt was docker-bg-sync, if you’re curious).
Docker for Mac users know: osxfs is just plain slow. NFS is a step forward, albeit with some tradeoffs. I’ve been experimenting with some different file mounting strategies in ddev, and I think I’ve found a winner.
