I've tested dozens of operating systems. Fedora 40 beta is the fastest I've tried
Briefly

Fedora 40 beta is remarkable for its speed, enhancing efficiency with instant app launching and results that seemingly anticipate user input. However, the GNOME Global Search may not deeply index folders as expected.
The overall look of Fedora 40 beta resembles its predecessors closely, with minimal surface changes. Yet, beneath the surface, it significantly improves speed in application responses and file management.
The new functionalities in Fedora 40 beta, including an expandable notifications feature and improved online account setups, greatly enhance user experience while maintaining a familiar interface.
Although visually similar to earlier versions, the Fedora 40 beta surprises with its speed, optimizing user interactions and operations across various applications, making the overall OS experience feel extraordinarily efficient.
