Summary

The latest CachyOS release, an Arch-based Linux distribution, focuses on delivering enhanced speed and performance through significant under-the-hood optimizations. It ships with kernel 7.0.0.1, which is a custom CachyOS kernel featuring a specifically tuned scheduler and options for BORE, sched-ext, BMQ, and RT. All applications in its repository are compiled for x86-64-v3, x86-64-v4, and Zen4 instruction sets with LTO, while core packages receive additional PGO and BOLT optimization. These enhancements result in improved swap performance, faster concurrent direct I/O writes with EXT4, self-healing XFS filesystems, and smoother 4K video playback. The distribution also offers extensive customization, including a Kernel Manager for selecting various Linux kernels and a choice of nineteen different desktop environments during installation.

Key takeaway

For Linux users seeking an Arch-based distribution with top-tier performance, CachyOS offers significant speed advantages due to its custom kernel and optimized package compilation. You should consider downloading and installing CachyOS if you require a powerful desktop OS for tasks like gaming, local AI, or video editing, provided you are comfortable with occasional terminal interactions inherent to Arch-based systems.
