CachyOS is committed to delivering high-performance computing to its users. Our installer detects your machine's microarchitecture and uses optimized packages for x86-64-v3 systems, providing a significant performance improvement of more than 10%.
All packages in CachyOS are compiled with LTO and optimized for the x86-64-v3 microarchitecture. We are currently working on adding a x86-64-v4 repository, which will be filled over time. The GCC compiler is optimized using PGO and LTO, and certain packages are further optimized with BOLT, a post-link optimizer.
CachyOS also includes several other performance enhancements to improve the overall user experience. These include:
At CachyOS, we place a high priority on security. That's why we've included the following security features in our software:
Ananicy-Cpp is a shell daemon that manages process IO and CPU priorities with community-driven rulesets for popular applications. This tool is primarily designed for desktop usage and is a complete rewrite of the original Ananicy in C++, providing lower CPU and memory usage. Additionally, Latency_nice has recently been included to help the scheduler make decisions about which tasks receive lower or higher latency.
