The Performance Of Arch Linux Powered CachyOS On AMD EPYC Servers
When kicking things off with a few different HPC oriented benchmarks, CachyOS and upstream Arch Linux had a nice showing. They were delivering slightly better performance over Ubuntu 25.10 and in turn the aging Ubuntu 24.04.3 LTS.
Very important as well is these additional incremental performance gains were being achieved without any increase to power consumption. CachyOS and Arch Linux were tending to tie or at be the forefront of delivering the best performance-per-Watt in these workloads.
There were some nice gains out of CachyOS and Arch Linux with the 7-Zip benchmark. Ubuntu 25.10 also performed much better than 24.04.3 LTS in the 7-Zip decompression performance. In this 7-Zip benchmark it's using the version of 7z shipped in the distribution repositories.
With the Zstd compression performance as shipped by each Linux distribution release, CachyOS and Arch Linux were tending to deliver measurable performance advantages over Ubuntu Server on this AMD EPYC Supermicro hardware.
