"Core Parking" will fully disable and power down unused cores that support "Core Parking". It takes a moment or two to "wake" the "sleeping" core, which causes the performance loss. It will also shift workloads to active cores so that only the needed amount of cores are "woken" from the ultra-low-power state. Disabling Core Parking removes the Ultra-low power staes, having the cores ready for new work.
As far as I understand it, teh WIn7 kernel isn't able to fully support CoreParking right yet, so maybe that's why there is no differnce in idle states or power consumption. It's more than possible that the cores aren't actually "sleeping" in Win7, and are merely ignored for thread-dispatch.
