Hello,

I recently upgraded my system from Fedora 41 to Fedora 42, and I have been experiencing performance issues. The system feels slow and not as responsive as before. Here are the details of my system :

Welcome to Fedora @ahmednn72

It looks like your swap is not working correctly, this could cause the less smooth experience.

What does your lsblk show?

Mine gives me with 16GB Memory a :

And what shows you the status message?

I also have performance issues since the upgrade to F42. Can you elaborate yours a little more?

In my case, applications/processes freeze for several seconds, but always in an isolated manner (so everythin else keeps working responsive). So far I had freezes of around 10 seconds of kate when I clicked in the text window to write something, Firefox when opening new tabs, the WiFi itself (I presume that was wpa_supplicant), and the sleep mode (when initiating sleep, the screen goes locked and freezes around 10 seconds before finally going sleep). Also, the desktop/KDE itself can freeze, and at a boot, I had the same issue with cryptsetup that did not respond some time until my encrypted disks had been decrypted and subsequently mounted (I already feared the system no longer boots :classic_smiley: ). But in all cases in which I could test it (firefox, desktop/KDE, kate), everything else worked fine and I could still do other things while they had been frozen.

My logs only indicate that processes sometimes don’t respond for some time, but at first glance not much more. However, I have not yet done a sophisticated check of what is going on, and did not yet review logs in detail. But when I saw your topic, I wanted to roughly summarize my case and see if that is about what you experience?

I have no taints in the kernel (taint = 0) and no nvidia, only default Fedora repos plus the mesa drivers from rpmfusion (I limited rpmfusion to these drivers’ packages). AMD Ryzen 7 PRO 6850U with Radeon Graphics. 6.14.2-300.fc42.x86_64. I have no swap but 32 GB RAM, which definitely is more than a normal Fedora installation needs. F42 KDE, originally installed at the time of F37. I hope I can spare some time in the next days to check this out more detailed, but my time is slightly limited these days :classic_smiley:

Anyway, would be good to check out if we experience the same thing, and see if we can identify (maybe also with others) what those who experience this issue have in common.

Supplement: I added kernel and KDE for now, the first as this could be linked to a kernel issue (including your elaboration as far as known), and as long as we cannot link it to something that explicitly is related to only Workstation, performance issues like ours are likely to be not linked to the DE, so it might be useful to also lead KDE people with performance issues here so that they can compare. I can split the topics later if we find out that its different. I hope that is in your interest too, otherwise I can remove it again - its your topic :classic_smiley:

If we find out that your issue is the same as mine, I suggest we remove nvidia (which I do not yet do to keep focused on your case), as it then is likely to be not related and only distracts in such a case.

In order to keep together all data that belongs together (which fosters solution of the issue for everyone affected), I suggested to consolidate experiences and what people have in common in the topic that already consolidates several cases: Consistent screen freezes after upgrading to F42 - #10 by airdiz → you might use this IF its elaborations apply to you. Feel free to add more information to help identifying what all have in common in order to identify what cases are the same, and what might be the origin.

I leave all other topics open as the elaborations of the three topics (this one, the one I just mentioned, plus No.3, and maybe more) do not yet make clear if that really are all the same issue. So if you think the one I mentioned does not apply to you but any of the other, you may of course keep posting there. But I suggest to mention your reasons in order to help delimiting the issues.

Everybody is free to open a bug report of course, but I suggest to invest the time to fill its fields carefully and produce and provide relevant data/logs that get attached, in order to get a real chance that a maintainer can pick it up (especially in times of a new release maintainers have to focus).

If you see more related topics that might resemble one of the existing ones, feel free to let them know about the others.

Howdy,

I am amazed by the masterful analysis presented by the posters here… I have some info that may be relevant to this issue.

I’m running Fedora 42 on a Brand new Vivobox with 40G memory. I run windowmaker and xosview (always).

I just noticed that the system is no longer using swap and the memory usage reported by xosview is MUCH reduced.

cat /proc/swaps
Filename Type Size Used Priority
/dev/zram0 partition 8388604 0 100

I have done the swapoff -va and swapon -va with NO change in behavior.

The kernel is:

uname -r
6.15.9-201.fc42.x86_64

It’s like the kernel has decided not to use swap anymore.

Just my 2 cents.

Need more info? Just ask, but could you include the command and switches necessary please?

Best regards,

George…

Do you think your system has a need for swap? Do you see physical memory usage getting close to the 40GiB you have ?

14

Usage of swap is not a good way to verify the system performance.
I have 32G of RAM and 8G of that is used by zram0 for swap. There is 26G of RAM unused for me.

As you can see below, swap usage is very minimal even when the system is continuously used for over 8 days uptime.

# uptime
 11:32:26 up 8 days,  2:07,  4 users,  load average: 0.35, 0.20, 0.12

 # free
               total        used        free      shared  buff/cache   available
Mem:        32775952     6356808      808212      187396    26268500    26419144
Swap:        8388604      100940     8287664

Swap is usually not used at all unless the system sees a need with processes being used that require more free RAM.

I edited your post and added the preformatted text tags so the formatting is exactly the same as seen on-screen with your inxi data. Those tags can be added by highlighting the pasted text then click the </> button on the toolbar above the text entry window, or by adding ``` on the lines immediately preceding and immediately following the pasted text.

Jeff,

Thanks for your help.

I’m noting that xosview showed a lot more memory useage for buffer cache which is different than I remember it.

I started looking around the system when a runaway script spawned a LOT of processes… eventually (as expected) freezing the system.

Note that mine shows almost all the available RAM as buff/cache as well as available. It will be used for apps when necessary
