partydrone PRO said over 2 years ago on Docker on Rails 7 :
 , I am very interested to know how larger Rails apps perform when developing with Docker Compose on an M1 Mac. Historically, Rails app performance is abysmal when the app gets larger. With several large apps I worked with in a Docker environment on Intel Macs, it often takes 30 seconds or more for pages to load in a browser. The culprit has to do with volume mapping from macOS into a Docker container (see https://github.com/docker/roadmap/issues/7). I tried using docker-sync in the past, and more recently Mutagen, but I'm anxious to see how the M1 Macs perform.
