Should I switch to CachyOS?

I am a vanilla arch user. I have install arch with both manual install and with archinstall in the past. But my question is “would i get any significant performance boost using cachyos if at all?” My cpu only supports x86-64v2. Or should I stick to my current install? What kind of optimizations does it come with?

Probably not. The optimized packages are only compiled for the v3+ repositories while the v1 repositories only contain AUR packages and other custom packages that don’t have any optimizations.

it will bring some more performance because the main boost brings cachyos-settings

If you want V2 you can read this ALHP/ALHP.GO: Go based buildbot to build official Archlinux repos with x86-64 feature levels, -O3 and LTO - ALHP.GO - SomeGit
It is not affiliated with CachyOS.

I’m using ALHP on my desktop pc, it’s been working well, you should try it.

V2. I have v2

Don’t expect big improvements.
Even from v1 to v3 they are not noticeable in daily use.

Incorrect statement, after adding the V3 repositories I notice a huge improvement! I was on pure Arch…
Now it’s more responsive and stable.
