Bitsum developed ParkControl because the core parking settings are hidden in Windows but can make a big difference, especially when it bursts CPU-bound loads (the most common type).
- Core Parking - CoreParking is a sleep state (C6), supported by most newer x86 processors, and newer editions of Windows. CoreParking deactivates the CPU cores dynamically to save idle power. Disabled cores are re-enabled when the CPU load increases again. This technology is very similar to frequency scaling because it wants to throttle the CPU at idle speed.
- effectiveness - Empirical evidence shows that deactivating core parks can make a real difference in system performance. There are many factors that determine how efficient it will be for any given system, including the CPU type, application load, and user behaviour. However, we find that Windows is often over-aggressive in its core parking, resulting in excess latency as cores are not packed to bursting loads (the most common type of CPU load).
- safety - These tweaks are completely safe for any PC that is properly set up. The only way that it could possibly cause a change in behaviour is when the PC has overheating problems. In such a case, these questions would be seen independently of these tweaks simply by placing a persistently high load on the CPU.
