> Do CachyOS optimizations actually make any difference whatsoever? I know they enable certain optimization flags whenever building software, but that doesn't directly equate to performance improvements unless you're actually benchmarking and testing it.

I switched from Windows 11 to Kubuntu a year ago, and then gave CachyOS a shot after hearing praise for it. I'm on a laptop with an AMD iGPU, and CachyOS's `znver4` optimized repos gave a significant bump on my Geekbench results:

(Note: these results are from almost a year ago though)

Lenovo Thinkpad P14s Gen4 AMD

- Windows 11: 2366 Single-Core Score, 10717 Multi-Core Score

- Kubuntu: 2496 Single-Core Score, 9878 Multi-Core Score

- CachyOS: 2569 Single-Core Score, 11563 Multi-Core Score

Repeat tests were essentially the same (Win11 23xx/107xx, Kubuntu 24xx/98xx, Cachy 25xx/115xx)

That's actually pretty great!

Have you observed any changes in your day-to-day usage, such as faster compilation times? If it's actually decently faster I might try it instead of playing with Gentoo to get better-optimized compilation flags.

I haven't benchmarked anything other than the initial tests with Geekbench. That said, it subjectively felt "snappier"/faster in terms of UI speed with KDE Plasma than Kubuntu. I've been a happy CachyOS user since.
