## What it is
A collection of performance-optimized Linux kernel packages for Arch Linux, built from the CachyOS kernel fork with multiple CPU scheduler options (EEVDF, BORE, BMQ) and compiler optimizations like Clang Thin LTO and AutoFDO. Kernels are offered in x86-64, x86-64-v3, x86-64-v4, and Zen 4 architecture-specific builds, plus specialized variants such as hardened, real-time, and release-candidate kernels.

## Use cases
- make my linux desktop more responsive under load
- kernel tuned for gaming on arch linux
- try different cpu schedulers like BORE or EEVDF
- build a kernel optimized for x86-64-v3 or zen4
- low latency real-time kernel for audio work
- hardened kernel with security patches
- reduce input lag and stutter on linux

## When to choose
- you run Arch Linux or a derivative and want a prebuilt performance-tuned kernel
- you want to experiment with alternative CPU schedulers without compiling yourself
- you game or run interactive workloads and want better responsiveness
- you want CPU-architecture-optimized kernel builds (v3/v4/znver4)

## When to avoid
- you need a vanilla upstream kernel for strict compatibility or certification
- you run a non-Arch distribution without adapting the PKGBUILDs
- you need long-term support guarantees rather than a rolling patchset
- you require a kernel for embedded or non-x86 targets
