"One of the goals on Microsoft's long list was to improve the performance of core Windows components like the Start menu and File Explorer. One of the strategies for making this happen is something Microsoft is calling the "low latency profile," which will speed things up by calling on an extra burst of CPU speed when users open Start or other apps and context menus."
"Windows Central has tested the low latency profile available in test builds of Windows 11 and observed a noticeable increase in speed and responsiveness on the same hardware compared to the current public version of Windows 11 25H2."
"Some users on social media criticized Microsoft for boosting performance this way, under the impression that it could increase power usage and decrease battery life, and criticized Microsoft for leaning on hardware rather than optimizing its software. Microsoft and GitHub VP Scott Hanselman responded to these complaints, asserting that the low latency profile is being added alongside other software optimizations and that "everything is a conspiracy when you don't know how anything works.""
""All modern operating systems do this, including macOS and Linux," Hanselman wrote of the CPU boosting behavior. "It's not 'cheating'; this is how modern systems make apps feel fast: they temporarily boost the CPU speed and prioritize interactive tasks to reduce latency." Paradoxically, letting your CPU or GPU use a lot of power in short bursts can save energy, relative to running at a lower power level for more time. This is called the "race to sleep," and basically all modern processors are designed to behave this way; as long as the CPU can return to a lower power state quickly a"
Microsoft is improving Windows 11 performance, focusing on core components like the Start menu and File Explorer. A key strategy is the low latency profile, which triggers an extra burst of CPU speed when users open Start, apps, or context menus. Testing in Windows 11 test builds shows increased speed and responsiveness on the same hardware compared with the current public Windows 11 25H2 version. Some users criticized the approach, claiming it could raise power usage and reduce battery life and that it favors hardware over software optimization. Microsoft and Scott Hanselman said the feature is paired with other software optimizations and that CPU boosting is standard on modern operating systems. They also noted that short high-power bursts can reduce energy use through “race to sleep.”
