Thank you for bringing this issue to us, we are investigating on this issue and we will update you on this issue after our findings.
Description
For quite some time we have been impacted by poor performance due to the nature of az-cli's command and module caching on it's first run. It would seem that az-cli was not written with ephemeral runners in mind, and it doesn't look like they could change this easily. Hence why we are opening this issue here.
We can see that the issue is fixed on windows images as a simple warmup has been implemented https://github.com/actions/runner-images/blob/c5c9a7cd7b2cfd20d740f7667fdaca8a412f2b52/images/windows/scripts/build/Install-AzureCli.ps1#L22
Can you please implement a simple warm up like on the windows runners?
From a sample of our logs we have measured the following impact Minimum 2 s Maximum 31 s Average 5 s
We estimate wasting roughly 6500 minutes per month which is more than 10% of our of total usage
