Android emulator performance on macos-11 Github Actions Runners

Performance characteristics of Android emulators on GitHub Actions

Lots of projects need to test android apps, and use GitHub Actions infrastructure to do so.

This document intends to show current timings for a sample workload, to inform what emulators are a good match for testing.

Test Conditions

  • We use the AnkiDroid androidTests
  • they are long enough to execute that they form a nice balance between cold start emulator time so neither dominates

How to connect a docker container to the docker daemon on a Synology NAS

Note: This originates from: https://forum.synology.com/enu/viewtopic.php?f=258&t=107508&sid=78d911737c5ecea1f9087bdab13612bf&start=15#p478281

Here are steps that I have modified to work for me. This assumes you have a shared folder named "docker" in volume1.

We need to Symlink /var/run/docker.sock to /volume1/docker/docker.sock, because Synology Docker GUI will not be able to run it when it's pointed directly to /var/run/docker.sock. Also the symlink needs to persist after reboot. To make it do so, you will need to create an automated task in your Synology DSM via "Task Scheduler".

  • Go to "Control Panel" > "Task Scheduler".
  • Click "Create" > "Scheduled Task" > "User-defined Script".
  • On the "Create Task: Window, make sure "User:" is selected as "root" and rename the "Task:" to whatever you like.
  • Click "Schedule" tab. Under "Date - Run on the following days", select "Daily". Under "Time - Frequency", select "Every 1 hour(s)" (just to be on the safe side).
