Except for KDE. At least compared to cinnamon, I find KDE much more responsive.
AI generated code will make things worse. They are good at providing solutions that generally give the correct output but the code they generate tends to be shit in a final product style.
Though perhaps performance will improve since at least the AI isn’t limited by only knowing JavaScript.
I still have no idea what it is, but over time my computer, which has KDE on it, gets super slow and I HAVE to restart. Even if I close all applications it’s still slow.
It’s one reason I’ve been considering upgrading from6 cores and 32 GB to 16 and 64.
Have you gone through settings and disabled unnecessary effects, indexing and such? With default settings it can get quite slow but with some small changes it becomes very snappy.
I have not, but also it’s not slow immediately, it takes time under use to get slow. Fresh boot is quite fast. And then once it’s slow, even if I close my IDE, browsers and everything, it remains slow, even if CPU usage is really low and there’s theoretically plenty of memory that could be freed easily.
Upgrade isn’t likely to help. If KDE is struggling on 6@32, you have something going on that 16@64 is only going to make it last twice as long before choking.
wail till it’s slow
Check your Ram / CPU in top and the disk in iotop, hammering the disk/CPU (of a bad disk/ssd) can make kde feel slow.
plasmashell --replace # this just dumps plasmashell’s widgets/panels
See if you got a lot of ram/CPU back or it’s running well, if so if might be a bad widget or panel
if it’s still slow,
kwin_x11 --replace
or
kwin_wayland --replace &
This dumps everything and refreshes the graphics driver/compositor/window manager
If that makes it better, you’re likely looking at a graphics driver issue
I’ve seen some stuff where going to sleep and coming out degrades perf
Hmm, I haven’t noticed high CPU usage, but usually it only leaves me around 500MB actually free RAM, basically the entire rest of it is either in use or cache (often about 15 gigs for cache). Turning on the 64 gig swapfile usually still leaves me with close to no free RAM.
I’ll see if it’s slow already when I get home, I restarted yesterday. Then I’ll try the tricks you suggested. For all I know maybe it’s not even KDE itself.
Root and home are on separate NVMe drives and there’s a SATA SSD for misc non-system stuff.
GPU is nvidia 3060ti with latest proprietary drivers.
The PC does not sleep at all.
To be fair I also want to upgrade to speed up Rust compilation when working on side projects and because I often have to store 40-50 gigs in tmpfs and would prefer it to be entirely in RAM so it’s faster to both write and read.
Don’t let me stop you from upgrading, that’s got loads of upsides. Just suspecting you still have something else to fix before you’ll really get to use it :)
It CAN be ok to have very low free ram if it’s used up by buffers/cache. (freeable) If Buff/cache gets below about 3GB on most systems, you’ll start to struggle.
If you have 16GB, it’s running low, and you can’t account for it in top, you have something leaking somewhere.
Lol I sorted top by memory usage and realized I’m using 12 gigs on an LLM I was playing around with to get local code completion in my JetBrains IDE. It didn’t work all that well anyway and I forgot to disable it.
I did have similar issues before this too, but I imagine blowing 12 gigs on an LLM must’ve exacerbated things. I’m wondering how long I can go now before I’m starting to run out of memory again. Though I was still sitting at 7 gigs buffer/cache and it hadn’t slowed down yet.

Have you tried disabling all local Trojans and seeing if that helps?

12/16, That’ll do it. Hopefully that’s all, good luck out there and happy KDE’ing
Have you tried disabling the file indexing service? I think it’s called Baloo?
Usually it doesn’t have too much overhead, but in combination with certain workflows it could be a bottleneck.
