SUMMARY

***

After the KDE update, I've notice a considerable overall sluggishness in opening application. Also opening krunner, even typing feel delayed and then hitting backspace. Everytime a charated is typed or deleting, I think a search operation is getting kicked off and this add to the delayed feeling.

My java trading application also now takes longer to open and become ready.

I am using KDE on openSUSE TW.

Can you do some basic troubleshooting? Like are there any apps or processes using lots of CPU time? Is your disk nearly full? Are you running out of memory? Etc.

A simple method to catch many sluggishness problems is running sudo atop. You will need to install atop if you do not have it installed already. But from there you can probably find the flashing red item that is responsible for the slowdown.

It's not the system, it's the KDE desktop it is just sluggish. I am doing nothing out of  the ordinary, happens all the time after. I've done is after a fresh reboot. It is not as responsive as it was in the past, before all the recent upgrades?

I've checked my disk, memory and CPU.
12 core CPU is 1% load.
62 GB free ram.
4TB free disk space.

I tired opening a few app they seem to be opening fine, much better than when I created this bug.

Definitely KRunner, it's not as responsive as it was before. Maybe this is it. I use it to do spell checks, conversions and running apps. The typing just seems poor. Sometime it misses key-strokes, backspace at odd time are delayed.

I recently had extreme sluggishness on my system which I eventually found via atop identifying that my SSD disk was very slow because it needed an fstrim. The report you are giving is very broad which makes it difficult to identify any culprit.

I've attached a screen shot from atop, don't see anything off.

I also notice now that spectacle also is a slight sluggish, because I could rapid hit my shortcuts and get screen captures. Now I notice, when I use my shortcut, there is a slight delay. So if I am fliping threw tab and capturing something. It will miss something, which was not the case before.
