It's worth highlighting that the M1 series has efficiency and performance cores. For our test suite, the efficiency cores struggle and can tank the whole test run.
We set our node test suite (jest) to use the number of performance cores, not the total count (which is the default).
That actually sped up the test process, particularly on the M1 which is 50/50 efficiency and performance cores. It's less pronounced on the M1 Pro, but still a benefit.
