Indeed, I found this change by Intel rather vindicating. In fact, that's why Intel went with on-chip managed core parking with Kaby Lake.

This is because the ramp-up time is non-negligible, or Windows is too aggressive, whichever perspective you choose to prefer. Hi all, since ParkControl was the OP here (excerpts and a link), I was given authorization to post here.Īs the OP mentioned, quoting from our page, disabling core parking can have a benefit on performance. And that is exactly the desired tweak for most users: disable parking only for high performance power plans.

That means you can, for example, disable core parking for the High Performance power plan, but leave it enabled for other plans. The core parking settings in Windows are implemented as parameters of power plans (aka power profiles). A number of complex parameters control when a core should be parked, and Microsoft tuned heavily towards power savings. Their interest was in conserving energy, even if this meant marginally decreasing performance. The problem is that Window's default power profiles are configured far too aggressively when it comes to core parking, especially on workstations. This technology is very similar to frequency scaling, in that it seeks to throttle the CPU when idle. Disabled cores are re-enabled as the CPU load increases once again. Core Parking dynamically disables CPU cores in an effort to conserve power when idle. Core Parking is a sleep state (C6) supported by most newer x86 processors, and newer editions of Windows.
