Windows 11 is testing an experimental option called Low Latency Profile. When this option is turned on, when the user performs key click operations (such as clicking the start menu button, right-click menu, and launching applications, etc.), it will instantly increase the CPU frequency within 1 to 3 seconds to shorten the UI response speed and prevent the user from always feeling stuck when performing such clicks.
After the news was released, many netizens participated in the discussion and believed that this was a sign of Microsoft's poor software engineering. That is, Microsoft did not think about how to optimize the operating system and underlying architecture to improve actual performance, but instead cheated by instantaneously overclocking the CPU. This is not the fundamental solution to Windows 11 performance problems.
Microsoft's vice president said that this acceleration mechanism itself is reasonable:
Hanselman, vice president of Microsoft's developer community, responded to user criticism on social media
Hanselman also explains why Linux systems are so fast: Linux menus feel very lightweight because Linux menus typically perform very little work and integrate very few services, not because Linux can circumvent CPU acceleration or background activity through some technical means. Application launchers on GNOME, KDE, and Linux still use a lot of CPU resources, actively schedule foreground tasks, and use modern CPU acceleration mechanisms.
Regarding users calling low-latency profiles a cheating and lazy practice, Hanselman also said that some netizens have a sense of conspiracy theory:Smart people are working hard to solve these problems, but a lot of the negativity is based on the intuitive assumption made by some enthusiasts with little computer science experience that when you don't know how anything works, everything is a conspiracy.
Of course, the lag problem may indeed be solved by increasing the instantaneous frequency of the CPU:
Regardless of whether Microsoft's behavior is cheating and lazy, the low-latency profile can objectively improve the response speed of Windows 11 by increasing the instantaneous frequency of the CPU, especially the response speed when clicking on the Start menu and the Explorer right-click menu. This is indeed a good thing for users who have been using Windows 11 for a long time.
Increasing the instantaneous frequency of the CPU will basically not have a negative impact on the battery life and heat dissipation of the laptop. Therefore, based on the current Windows 11 usage experience, as long as it can improve the actual usage experience, even evil repair methods are acceptable. After all, rather than tolerate the lag problem for a long time, it is better to make full use of modern CPU performance to improve the experience.
