CachyOS suggests it is fast and secure, but what security changes does it make over Arch Linux, and is it worth a shoutout on the OS guide?
One immediate concern is it appears they are sponsored by Cloudflare.
CachyOS is “fast” because it features a new kernel scheduler (potentially increasing responsiveness under load) and microarchitecture optimized repositories (generally a 0-15% CPU performance increase).
As far as security, there isn’t really any improvement over Arch. Their repos build a select bit of AUR software, so if you install the packages in question, you’re trusting those devs as well as the CachyOS devs.
They compile more software with clang and with LTO to increase performance, but their repositories are out of date compared to arch (which is worse for security)
Only if the cachyos devs were to build the AUR packages blindly, which I doubt they do
