Real-Time CPU Optimization and Automation
Process Lasso ProBalance Technology improves PC responsiveness, eliminating micro-lags. Process Lasso also includes the Bitsum Highest Performance Power Plan that disables CPU Core Parking and Frequency Scaling for maximum bursting performance.
ParkControl Pro
CPU Parking is a low-power sleep state (C6) supported by most modern processors and operating systems. It dynamically disables CPU cores in an effort to conserve power when idle. Unfortunately, this power saving comes at a price: Latency when CPUs need unparked to execute code.
Initially, core parking was controlled entirely by the operating system. The aggressive core parking of Windows led to a great deal of inefficiency during bursting CPU loads. Intel moved core parking control onto the chip in the Skylake generation, and AMD followed, but still the parameters of the Windows power plans are set to aggressively park CPU cores. Even the default ‘High Performance’ power plan is not immune. The new ‘Ultra Performance’ power plan copies what Bitsum did with our own ‘Bitsum Highest Performance’ power plan and finally disables core parking entirely.
ParkControl (and Process Lasso) not only let one more easily configure CPU core parking and frequency scaling, but also allow for dynamic entrance into a higher performance power plan. For instance, with Process Lasso, you can automatically enter ‘Bitsum Highest Performance’ will you start a game, then go back to ‘Balanced’ when you exit.
ParkControl has Dynamic Boost to allow you to set active and idle power plans. Process Lasso has a similar feature with its IdleSaver.
Efficacy
Empirical evidence shows that disabling core parking can make a real difference in system performance. There are many factors that will determine precisely how efficacious it will be for any given system. However, generally, Windows is too aggressive in its core parking, resulting in excess latency during bursting CPU loads (the most common type).
How to Restore Defaults
Any changes you make with ParkControl are easily reverted. To restore the default power plan settings:
Changing Parking Settings Using PowerCfg.exe
You can also change these settings via Window’s Powercfg.exe. You must run this utility with elevated rights, so be sure to open an elevated console window by right-clicking ‘cmd.exe’ and selecting ‘Run as Administrator’.
Note that these commands adjust the currently active power profile. You can adjust specific ones by using their GUID, or switching to them prior to running these commands.
First, backup ALL your Power Settings by creating a dump of everything to a TXT file. It is unlikely you will ever need this, but…
To mandate 50% of available cores always remain unparked, run:
To adjust it so that only 25% of available cores remain active at all times, allowing 75% of available cores to be parked, you’d run:
‘0’ indicates to park as many CPU cores as possible.
To enable maximum use of CPU Parking for the power profile you are currently using:
To disable CPU Parking completely for the power profile you are currently using, you’d want to run:
All the above configure core parking while the system is plugged into AC power. For DC (battery) power, core parking is usually forced, but to configure it you would instead use ‘-setdcvalueindex’.
APPLY New Settings, NOW!
After changing the power scheme settings for CPU Parking as desired, you then want to make the changes active by running the command:
With ParkControl, a reboot is NOT required for these changes to take effect – in contrast to direct registry edits or other core parking software.
After applying tweaks, check the Windows Resource Monitor (resmon.exe) and verify that CPU Parking is indeed as you intend.
How to Show Core Parking Options in Advanced Power Options
This gets tricky because not all settings apply to all models. There is, however, a general ON/OFF switch that DOES apply to all CPU models. Below we’ll present the most commonly used simple ON/OFF core parking switch, and how to show it in the Windows Advanced Power Options without any registry edits!
Execute the following commands to hide or un-hide the primary ON/OFF switch for core parking in the power plans.

Core Parking and Intel Skylake and Above
Due to the inefficiencies of OS managed core parking, Intel took over core parking in Skylake and above. These thus have different core parking settings. The most important may simply be the ON/OFF switch of it’s Autonomous Mode, though there is also an aggressiveness %.
Autonomous Mode turns on/off the CPU’s ‘smart parking’, but does NOT turn off OS managed core parking. To do that, use ParkControl or the usual ways.

Re-hide Skylake+ Core Parking Settings without direct registry edits (real-time, no reboot required!):
Importantly, Skylake adds an ‘Autonomous’ mode that you turn on or off to disable core parking. Within this is a percentage to adjust it’s aggressiveness.

Bitsum Highest Performance Mode
Process Lasso’s Performance Mode induces the ‘Bitsum Highest Performance’ power plan that keeps your CPU ready to execute code at all times. This eliminates latency otherwise encountered while bringing the CPU out of a low power state. This especially benefits bursting CPU loads, which are the most common real-world CPU use pattern.
With ParkControl, we revealed hidden CPU settings that control core parking, and wrote about how CPU core parking and frequency scaling can affect performance of real-world CPU loads. Put simply, these power saving technologies come with a performance trade-off, so they should be disabled when maximum performance is desired.
Both ParkControl and Process Lasso offer a power profile, Bitsum Highest Performance, that is pre-configured for ultimate performance. In this power plan, your CPU always remains ready to execute new code. Core parking is disabled and the CPU never drops below its nominal (base) frequency.
Since you probably don’t want to be in this power plan all the time, we include automation to switch the active power plan when specific applications or games are running (Performance Mode), or only when the user is active (IdleSaver).
Process Lasso also allows for specific power profiles to be associated with an application in case you want to use different power plans.
Finally, the IdleSaver feature of Process Lasso will switch to a more conservative power plan when you go idle. Similarly, ParkControl has a function called Dynamic Boost that is essentially the opposite of IdleSaver – it raises to a more aggressive power plan when the system is active.
Choosing an alternate power profile for Performance Mode
Users can choose a different power plan than Bitsum Highest Performance (BHP) to use with Process Lasso’s Performance Mode. To do this, select the application menu item ‘Options / Power / Performance Mode settings / Select power plan to use‘.

Система ⇒ Bitsum ParkControl Pro 1.6.0.10
ParkControl разработан компанией Bitsum и предназначен для управления настройками парковки ядер. Эти настройки скрыты в операционной системе Windows, но имеют серьезное влияние на производительность, особенно при импульсных нагрузках процессора (самый распространенный тип нагрузок). После того, как разработчики инструмента обнаружили данные зависимости, Intel приняла решения по переносу управления парковкой ядер из операционной системы в аппаратные средства, подтверждая выводы Bitsum.
Bitsum Highest Performance. Схема электропитания, которая позволяет автоматически оптимизировать аппаратные компоненты для максимальной производительности, превосходящей по показателям возможности стандартной схемы управления питанием “Высокая производительность” в системе Windows.
Bitsum Dynamic Boost. Автоматическое переключение планов питания при переходе компьютера в режимы активности и бездействия. При активном использовании ПК оставайтесь в режиме Bitsum Highest Performance.
Bitsum Dynamic Boost предназначена для динамического изменения плана электропитания, когда компьютер активен и для снижения потребления ресурсов во время простоя системы (функция доступна только в версии 1.1).
Эмпирические данные показывают, что отключение парковки процессоров может привести к серьезной разнице в системной производительности. На эффективность данной меры для отдельной системы влияет большое количество факторов, в частности тип процессора, загрузка приложений и поведение пользователя.
Тем не менее, Windows проводит очень агрессивную парковку ядер, что приводит к избыточным задержкам, потому что ядра «снимаются с парковки» во время импульсных нагрузок.
В тестах Bitsum наибольший выигрыш от отключения парковки удалось получить с процессорами AMD. Это связано из-за разницы в том, как процессоры AMD распределяют вычислительные ресурсы между логическими ядрами. Microsoft оптимизировала ОС под технологию HyperThreading от Intel, которая меньше полагается на вторичные ядра. Вторичные логические ядра AMD являются практически полноценными процессорами.
Настройки ParkControl являются полностью безопасными для любого компьютера, который работает исправно. Единственный возможный сценарий поведенческих изменений связан с потенциальными проблемами перегрева компьютера. В этом случае эти проблемы будут возникать независимо от применяемых параметров, просто за счет серьезной нагрузки на процессор.
