Platform Market: Windows 11 adds Low Latency Profile for faster app launches
Microsoft has introduced a new "Low Latency Profile" in Windows 11 that speeds up application startup by briefly increasing CPU performance. The feature is delivered with the August update KB5121003 and alters CPU usage during app launches so the processor can run near full capacity for short bursts. Tests reported by Windows Latest show meaningful reductions in load times for Web-based apps (for example, the Weather app loading time fell from about eight seconds to four). The update is rolling out in waves to users.
An OS-level performance change from Microsoft can affect app startup times, resource usage and user experience; relevant for app developers, performance monitoring, and any in-app experiences including advertising and measurement.
