The first benchmark installs Drupal, using the codebase. Since around 2016, support has been around (albeit barely documented) for NFS volumes in Docker (see Docker local volume driver-specific options).Īs part of my site migration project, I've been testing different local development environments, and as a subset of that testing, I decided to test different volume/sync options for Docker to see what's the fastest-and easiest-to configure and maintain.īefore I drone on any further, here are some benchmarks: Since then, the File system performance improvements issue has been a common place to gripe about the lack of improvements to the underlying osxfs filesystem. It was painfully slow, and the community finally got a cached mode that offered a 20-30x speedup for common disk access patterns around 2017. So, read on.Įver since Docker for Mac was released, shared volume performance has been a major pain point. September 2020 Update: Alas, Docker for Mac will not be getting built-in Mutagen support at this time. Hopefully that feature makes it to the standard Docker for Mac version soon. July 2020 Update: Docker for Mac may soon offer built-in Mutagen sync via the :delegated sync option, and I did some benchmarking here. But it's actually fairly performant using the barely-documented NFS option! It's acceptable (but still very slow) if you use the cached or delegated option. Tl dr: Docker's default bind mount performance for projects requiring lots of I/O on macOS is abysmal.
