The `pytest -n auto` switch does not give the accurate maximum number of parallel tests we can run. It uses the number of CPUs not the number of cores. It seems that the `--auto` switch runs as many pytest processes as many CPUs we have, not as many cores we have. The Helm tests utilise ~70% of available CPUs when the CPUS have dual cores, so we shoudl be able to gain ~10 minutes (from 32 to 22) when Helm tests are run on self-hosted runners, and likely even more - 13 minutes - 32 m instead of 45m when run on Public Runners. <!-- Thank you for contributing!
