Redox OS introduces multithreading by default and improves performance.

8 October 2025 08:14

The developers of the Redox OS operating system, written in Rust, have enabled multithreading support by default for x86 systems. Previously, the feature was experimental, but after some bug fixes, it has become an integral part of the platform. This provides a significant performance boost on modern computers and laptops.

Redox OS was developed from the ground up and implemented entirely in Rust, a language focused on security and fault tolerance . Switching to a multithreaded model allows the system to use CPU resources more efficiently and execute parallel tasks faster, which is especially important for desktop and server scenarios.

Additionally, the team introduced several important optimizations. Small file handling has been improved, system installation has been speeded up, and LZ4 compression support has been added to the RedoxFS file system.

Developers call these changes a “major step” in improving the speed and responsiveness of the operating system.

The update also includes improvements to the apps and user experience. These improvements affect the core tools and interface, making the system more stable and easier to use in everyday use.

A convincing demonstration of the project’s capabilities was the successful launch of Redox OS on the BlackBerry KEY2 LE and Google Pixel 3 smartphones. Although these are still test builds, the developers emphasize that the kernel and driver model are already versatile enough for mobile devices.

Redox OS remains one of the few operating systems developed from scratch in Rust and independent of Linux or BSD code. The project develops its own file system, kernel, and environment, making it a unique example of a “pure” Rust approach to systems programming.
