Bar chart depicting Drupal 10 install time, in seconds, with various configurations on an M1 Mac

I wrote about performance comparisons between Docker Desktop and Colima on macOS both with and without Mutagen in March, 2022, and wanted to update the numbers. Things are looking great everywhere. There are now many more permutations, though. Colima has 9p and VirtioFS file mounting, and Docker Desktop’s VirtioFS implementation now works well (and is fast!).

(Edited 2022-12-28: Colima version 0.5.2 solved a couple of significant performance problems with VirtioFS mounting, so I updated the fantastic numbers and removed the caveat about ddev import-db being slow.)

Methodology: I tested each of these permutations with both a Puppeteer script to do a web install of Drupal 10 demo_umami and also a drush command-line install (ddev mysql -e "DROP DATABASE IF EXISTS db; CREATE DATABASE db;" && ddev exec killall -USR2 php-fpm && rm -rf web/sites/default/files/* && ddev mutagen sync && time ddev drush si demo_umami -y). I tried each 3 times to make sure that the numbers were tracking reasonably, and then took the mean. The Drupal 10 installation is a very heavy web activity that touches thousands of PHP files, and it’s a sequential operation with a fixed timeline, so it’s a tempting thing to use for benchmarking.

As usual, the command-line installs basically tracked about twice as fast as the web-based installs, which was no surprise, so I didn’t include charts for them, although they’re available in the source data.

The bottom line is that any setup with Mutagen can do a D10 install in 25-40 seconds, which is astonishing (there was a time that it took 5-6 minutes on most platforms). And even without Mutagen, the VirtioFS mounts can do it in 60-80 seconds on both Docker Desktop and Colima.

If you’re interested in Colima with DDEV, see the docs. It’s super easy to set up, and even though it’s a young project, it’s well-maintained and people have been having good experiences with it. And for those of you concerned about Docker Desktop’s new subscription license fee, it’s a great option. But as you see here, it’s a great option for other reasons.

And of course, if you haven’t tried out Mutagen with DDEV on macOS, it’s time. Run ddev config global --mutagen-enabled and ddev restart and you’re on your way, see DDEV docs. Although we were all worried about filesystem consistency originally, the feature has turned out to be shockingly reliable, but read the docs for caveats.

Some takeaways from this round of testing:

  • Everything is faster than it was early this year, sometimes by a lot.
  • Docker Desktop VirtioFS has made incredible progress. Now with macOS Ventura 13.1, Docker Desktop 4.15.0, the promise has met reality. It’s super fast, and seems to be reliable. The problems that plagued it for most of the last year seem to be resolved, permissions, ownership, and DDEV custom commands work right. In March 2022, it wasn’t usable, but now it’s great. It’s really, really fast with Mutagen enabled, but quite usable even without.
  • Colima with 9p mounting is nearly unusable – I wasn’t willing to wait for it to complete the install. Even though I show it in the graph as taking 150 seconds, the reality is it would have taken 600 or more, but that would have skewed the graph and I was impatient. (Note that 9p is the default mount type in Colima 0.5.1, so don’t use it right now). I recommend that you use mountType: sshfs to start in Colima, but experiment with mountType: virtiofs if you’re on macOS Ventura.
  • Mutagen remains a great default choice, but Colima and Docker Desktop VirtioFS are probably now adequate choices if you want complete consistency. (Although they passed my casual tests of the things that used to break, I don’t have many real-world reports of what happens when people use these without Mutagen.)
  • At this writing there is a bug in Colima where some upgraded instances aren’t mounting at all. Make sure in your ~/.colima/default/colima.yaml mountType is not empty; change it to sshfs or consider virtiofs if you’re on macOS Ventura.
  • For DDEV + Colima I still recommend the conservative --mount-type=sshfs --vm-type=qemu but the more adventurous of you will have fun with --vm-type=vz --mount-type=virtiofs, and it remains wonderful to work with Mutagen enabled in DDEV. I look forward to hearing your feedback.

Congratulations to the Colima, Lima, and Docker Desktop, and Mutagen teams for an amazing year of progress!
