GH Actions: speed up slow jobs by using Linux Arm64 #791
Conversation
GitHub has made Linux arm64 runners generally available and running tasks on these images instead of the traditional images can deliver up to a 40% performance boost. As the fast majority of end-users won't be using Arm yet, I'm not (yet) switching all Linux builds to Arm runners, but for now, I think it makes sense to try and speed up the build by using these images for the slowest builds (PHP 5.4).

The changes here look good to me. I think we can switch over all the PHP 5.x builds without much impact.
I see that we'll need to set COVERAGE_REPORTER_PLATFORM so that the correct flavour of binary gets installed for the Coveralls part to work successfully. Ideally that fix gets pushed to the script itself rather than having to set the variable, as uname -m will give the value that they're looking for. See coverallsapp/github-action#218
Edit: This change should make the tests pass here. coverallsapp/github-action#238
@fredden I was just about to look at the build failure when I got interrupted by a phone call. Thanks for finding the root cause so quickly! coverallsapp/github-action#238 looks like magic to me. 🙌🏻 I'm going to give it a few days, but may just update this PR with the |

@afinetooth That's awesome! Thank you for working with us on this. Once the release is out, I will rebase this PR to retrigger the build and 🤞🏻 |
