Awful performance since install

I took the inxi from your other thread …


Now starting there.

You have an AMD video card … the best driver is the open source AMDGPU.
Theres nothing proprietary to want.
(theres some slight caveat to that with 3D rendering … but then you just want those proprietary components… and its besides the point here)


Kernel 6.5 is EOL (end of life).
See kernel.org
Please install a supported LTS and remove 6.5.
ex:

sudo mhwd-kernel -i linux66

Then reboot and select 6.6 from the menu.
You can double check the running kernel using uname -a.
Once not booted into 6.5 you may remove it.

sudo mhwd-kernel -r linux65

Your BIOS is out of date


You also have a small amount of memory and no swap. When you use those 6GB of RAM then your system will lock up.

It appears you are using the majority of it already. So I expect it probably runs out pretty easily.


Theres a number of other things that might be worth checking … but I would say handle those things first.

Recap;

  • Install LTS kernel and remove 6.5. See above.

  • To update the BIOS please refer to the manufacturers documentation. You will either be able to update using the UEFI/BIOS itself (load the update from a file using the administration screens), or you can use a windoze (either from Dual-Boot, or from a live system such as Hirens Boot CD).

  • Enable SWAP. You can choose any flavor, such as a swapfile, and so on.
    My suggestion is zram. See below.

Click for zram instructions 
sudo pacman -Syu zram-generator

Then edit the configuration file. (use your preferred editor)

sudo micro /etc/systemd/zram-generator.conf

You want it to look like:

[zram0]
zram-size = ram / 1
compression-algorithm = zstd
swap-priority = 100
fs-type = swap

You may want to ensure zswap is disabled as well. One way is to add to the boot options, at /etc/default/grub the option zswap.enabled=0.
That is to add it to one of the CMD lines so that (Assuming no other options) it would look like:

GRUB_CMDLINE_LINUX="zswap.enabled=0"

Then run

sudo grub-mkconfig -o /boot/grub/grub.cfg

And reboot.
You can check the configured swap/zram using

swapon

zramctl



Ultimately the main cause of

is your memory/swap situation. With about 99% certainty.
But the other points should be handled as soon as possible as well.
