KDE laggy even if I use default theme

@JiaZhang

Since you just did a fresh install, it’s probably the SSD that just need some time to accustom itself.

I don’t know what you’re talking about here.

@lux_nychta

If it can help you, I just made a video to show you an example of freeze

I don’t really see the issue you’re talking about, what is freezing?

//EDIT: also it may not be the issue but your BIOS is really outdated (from 2019). If you update it be prepared with a Manjaro live USB to boot your installation as it may be possible the BIOS doesn’t auto detect the bootloader (and you can use the Manjaro USB to “Detect bootloaders” to boot on Manjaro, and from there you can reinstall Grub with command sudo grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=manjaro --recheck for an UEFI installation, followed by sudo update-grub and reboot).

That’s some proprietary HDD / SSD design stuff companies won’t tell publicly:

Manjaro kde open app quite slow compare to other distro(nitrux)/manjaro gnome/mamjaro i3

Is this a fresh installation on a partition in which the disk space is previously unused? On SSD drives, generally you need to use the firstly used drive space for longer time to let the SSD “accustom” itself (internal paging, caching layer if available, etc depending the SSD technology). So you might want to use Manjado KDE for a longer time first, say 1 week.

OP expected an instant response. Different people have different expectation on responsiveness.

when I click, the menu disappears (normal) and near to the cursor there is little logo which is “jumping”.

And if you take a closer look, you can see the logo stops and resume its “jump”

I know it’s a little freeze but I take this example because it’s the only one I can predict. Others appear sometimes

That’s just different people taste on responsiveness. I’m also like you so I can see that this kind of freezing is annoying. I also assume that you’re also bothered with the slight lag when pressing the “Configuration” button and other similar things.

That kind of freezing is more to the kernel process load stuff and lots of things contribute to this (your CPU is still the good Ryzen generation, so the SSD initial state is probably the bottleneck), but it’s definitely not a graphics problem.

[lux_nychta]

I’ve never heard of it but ok I’ll wait a bit to see if the problem goes away

Just out of curiosity, do you have any resources on this SSD initial state behavior?

[JiaZhang]

I don’t have a good resource actually. Internet won’t give you the details. Most I learnt from heavy-reading textbooks and experiences.

What I can briefly explain about initial state is something like caching; you need to wait for a longer time to get good performance.

Many things are proprietary implementations and what the public knows about HDD / SSD is abstraction.

But overall, not saying that SSD is the real bottleneck here, it’s the most probable. There are many things to consider like KDE code implementation or main memory bottleneck …
