Added to the in-development Linux 5.16 kernel was cluster-aware scheduling designed to enhance system performance where groups of CPU cores may share caches or similar and thus the scheduler could benefit from knowing that information for making more optimal task placement. But as I pointed out early on with Linux 5.16, this cluster scheduling is hurting the Intel Alder Lake performance on the new kernel. Intel is now working to correct this by making the cluster scheduling configurable and disabling this functionality by default for hybrid CPUs such as Alder Lake.
