CachyOS
CachyOS is a Linux distribution based on Arch Linux. It focuses on speed and security optimisations - the default Linux kernel is heavily optimised using the BORE (Burst-Oriented Response Enhancer) scheduler, while the desktop packages are compiled with LTO, x86-64-v3 and x86-64-v4, Zen 4 optimization, security flags and performance improvements.
