Inconsistent Xcode cloud performance

Hi!

For the past few days I have been experiencing slower builds in my workflows, without a clear reason of the cause as sometimes they run with the old usual time.

I tried contacting the Developer Support without success in finding out the reason of these issues, the case number was 102661768064.

As an example, I have a workflow for Pull request checks that involves testing and analyzing. This usually ran for 11-15mins, but now it could take up to 30mins or more. Looking into the logs it just seems that the machine it's particularly slow, then in another build it goes with usual times again.

As an example, below are the summaries of two builds of the same branch:

Being in the free tier, these new long times are burning my free time quite faster and probably will need to look into running this checks in GitHub Actions if it doesn't improve.

A hint of what might be wrong is also found in an error in the test workflow, which denotes a problem booting a simulator.

Any help on this will be appreciated, thanks!
