that was thorough, thank you.
I wonder what there own ‘take’ on core, extra, and multilib stuff is?
It would be kind of cool to run another set of compatible guts inside your existing shell/setup, as macabre as that sounds :).
It would have to be an improvement or benefits I could understand before I would undertake that. Honestly, I just love that one is able to. Thank you again.
ALHP’s take is just to provide packages that are build identical to Arch except they are compiled enabling additional, modern CPU features, which can lead to improved performance. But that is not a broad “everything gets x% percent faster”, but depends on the application. There’s a good chance you wont even notice if you don’t run one of those special cases.
Arch doesn’t do that because they don’t have the infrastructure in place to provide architecture specific versions at the moment, and requiring a higher baseline would exclude people who are below it. So Arch ships the most common denominator to everybody.
Just to throw a phoronix benchmark around: https://www.phoronix.com/review/cachyos-x86-64-v3-v4/2
So usually there isn’t a downside, you potentially just leave some performance on the table, but don’t expect a miracle.
PS: Cachy on the other hand is pretty opinionated on providing patched packages in many places.

So far I’m happy with having added the CachyOS repos to my system, it’s still just Arch just with some extra repos. I have not tried ALHP but since I had been reading a lot of people saying how good CachyOS was I decided to go with their repo instead of the ALHP repos. Just having a quick glance at the ALHP repos it seems to do all packages while CachyOS repos just has a few selected packages plus some extras.
I want to think (I haven’t really analyzed the repos) that they have wisely chosen those that would benefit most by better CPU utilization (I notice things that I would consider would benefit are indeed in the cachy opt’d repos). Ie the obvious low hanging fruit.
Not sure what exactly you are saying but it sounds like that ALHP repos are well thought out since they are just clone the Arch packages with cpu optimizations. That CachyOS repos are more what you would consider obvious benefits, as those obvious things is what CachyOS is known for. Did I understand that correctly?
I think so?
I mean I don’t think the ls command or the cd command have much advantage to being more efficient, where as the display driver and something like ffmpeg do.
Cool! 
I was just wanting to make sure I understood your last reply. As it was a bit confusing, my first language isn’t English that’s why I was asking.
I’m bored, so I tried the Cachy repos, can’t remember how many packages it installed, but it was north of 1300 (was on the phone…).
Rebooted, no issues, but my perception is my machine,
(Ryzen7/RTX3070), feels snappier, a lot snappier.
I used the curl/script from their website.

That’s my perception too (though I used a full blown reinstall).
I had my ventoy USB plugged in ready for it to fall flat on it’s arse 
Didn’t need it, but it was a bit “Squeaky bum time” as we say in the UK!
