The recently published release of the distribution Cachyos 2412221 is based on the ARCH Linux package base and utilizes a continuous model of update delivery. This distribution is known for its optimizations aimed at enhancing productivity and offering a variety of desktop environments for installation. Apart from the default KDE environment, users can also opt for gnome, xfce, i3wm, Wayfire, Lxqt, Openbox, Cinnamon, Cosmic, Ukui, Lxde, Mate, Budgie, Qtile, Hyprland, and Sway. The installation ISO-image size is 2.7 GB, with a separate assembly (2.8 GB) available for wearable devices in handheld edition featuring a Gamemode style interface and components tailored for gaming enthusiasts.
The default distribution planner includes a problem planner called bore, optimized to minimize desktop delays and elevate the priority of interactive processes. The kernel and packages are compiled with LTO-optimization (Link-Time Optimization) and support for instructions found in processors based on microarchitectures X86-64-V3, X86-64-V4, and Zen4. Furthermore, PGO optimization (Profile-guided Optimization) or bolt (Binary Optimization and Layout Tool) is included when assembling the core packages. The distribution comes with the Cachy-Browser, a web browser based on Firefox with security enhancements and performance improvements from the Librewolf project. Users can choose from file systems like BTRFS, ZFS, EXT4, XFS, and F2FS.
Main Changes:
- The default Linux kernel is compiled with autofdo optimization using profiling results to enhance performance for frequently executed operations. The Clang 19 compiler is used to build the kernel, and the optimization profile for Cachyos is tailored to tasks like Sysbench and Cachyos Benchmarker performance tests, GIT operations, and kernel compilation from source code.
- A Rustical driver, written in Rust and utilizing the
