Are CACHYOS users always enjoying optimization?

General

Since I had been using ARCH prior to CACHYOS, I am habituated to daily system update. So is the case with CACHY. But I have seen that sometimes updates are installed from unoptimized repos like extra, core, etc. instead of cachyos-v4. But after 1 or 2 days however they are updated again from cachyos-v4. So prior to cachyos-v4 update I had been using unoptimized packages. Am I right ??

Yes and no.

There are several repos where packages come from and IIUC packages from Arch are v1, whereas cachyos packages also are v1. Packages from cachyos-v3 are v3, etc.

You can see this here:

v1:

Installed From  : cachyos
Name            : yay
Packager        : CachyOS <admin@cachyos.org>

Installed From  : multilib
Name            : wine
Packager        : Felix Yan <felixonmars@archlinux.org>

Installed From  : extra
Name            : wayland-protocols
Packager        : Jan Alexander Steffens (heftig) <heftig@archlinux.org>

v3:

Installed From  : cachyos-v3
Name            : zstd
Packager        : CachyOS <admin@cachyos.org>

Installed From  : cachyos-core-v3
Name            : xfsprogs
Packager        : CachyOS <admin@cachyos.org>

Installed From  : cachyos-extra-v3
Name            : xorg-xwayland
Packager        : CachyOS <admin@cachyos.org>

So you usually have a mixed system but that’s okay.

Thanks for the info. But on my system optimized packages are from cachyos-v4. But v1 and v4 doesn’t matter to me. Just enjoying the snappiness. Only packages I use are Gnome desktop, firefox, libreoffice, kicad, inkscape, Zoom(AUR) and STM32CUBE IDE (ST Microelectronics). All run fine. No issues.
Zoom and STM32CUBE are free but proprietary. I think they are not optimized.

These were examples from my installation using a Zen 3 AMD CPU.
Your CPU supports v4, so your installation will prefer v4 to v3 to v1.
It will take the most optimized packages available and supported by your platform.

stm32 stuff are java based (/eclipse ?) , if you want optimisation I would check the java version used and its params/optimisation … very often you can already make the fonts better looking

We are using the archlinux packages in following cases:

  • Failed build with opti or other issues
  • Packages with the “arch” *-any
  • Haskell packages

Thanks. Got it.

Yes it is eclipse based. But it is fully maintained and distributed by ST. I think it cannot be tweaked easily. If done, then I have to manually take care of everything during update. But on my CACHYOS system the default install is fine including fonts.
