The problem seems to be specific to the Intel Alder Lake and probably Raptor Lake processor families. With Win 22H1, the python programs in the PowerShell were assigned to the performance cores. Under 22H2, they now seem to be allocated to the efficiency cores, resulting in the performance hit. I observed the core utilizations using Resource Monitor and XTU. Disab
