CPMaxCores

CPMaxCores specifies the maximum percentage of logical processors (in terms of logical processors within each NUMA node) that can be 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 50% ensures that no more than 8 logical processors are ever in the un-parked state at the same time. The value of this setting will automatically be rounded up to the value of CPMinCores.
