CachyOS Repository General Information

Why does CachyOS utilize its own repositories?

Performance and optimizations

We want to provide a performance-optimized distribution and this requires performance-optimized packages. Currently we are recompiling the Arch Linux repository core and extra with the generic x86-64-v3 and x86-64-v4 instruction set.

  • x86-64-v4 - Enabling of AVX512, which can highly benefit at applications
  • x86-64-v3 - 5%-20% performance uplift

Customized Packages

In the CachyOS-PKGBUILDs we are maintaining a bunch of packages, which are getting patches, PGO or BOLT Optimization to provide an additional performance uplift.
