CPMinCores

CPMinCores specifies the minimum percentage of logical processors (in terms of all logical processors that are enabled on the system within each NUMA node) that can be placed in the un-parked state at any given time.

For example, in a NUMA node with 16 logical processors, configuring the value of this setting to 25% ensures that at least 4 logical processors are always in the un-parked state. The Core Parking algorithm is disabled if the value of this setting is 100%.
