KDE Will Nicely Notify You When Apps Are Being Killed Due To Out-Of-Memory

Maybe consider optimizing/rewriting Plasma first:

The absolute worst DE in terms of RAM consumption on Linux. I can redo the comparison but so far no one has been interested.

In my tests vanilla plasma uses about a half of RAM than vanilla gnome. Just for noting, fedora or red hat are not good environments for plasma, their buids are just terrible, it's a known issue for years now. Try using kubuntu, neon or openSuse.

You are so wrong. Plasma uses only ~700MB on my computer...

Plasma only uses 500MB on my PC, and that's with other applications actively running. I have 32GB of RAM, so it's not like Plasma needs to be this frugal but it is anyway. But Avis is a known anti-Linux troll so... feel free to ignore him in the future. He's just engagement farming.

They should really hire some ui/ux specialists to align the elements on their panels properly…

All work are voluntary, I'm sure they will be happy with some help, and very open too. You don't even need to code, but just open a bug with some images for the better alignment will herp a lot

GNOME has a memory leak with the Nvidia driver and will happily use 10GB+

Fedora is actually a good choice for this type of testing since the DEs are basically vanilla upstream. E.g. on OpenSUSE the Xfce experience is better than default upstream because they make changes like using Whisker Menu, but those changes also invalidate DE RAM usage comparisons.

biggest fault here is that Fedora KDE defaults deploy by default Akonadi. So first fix Fedora defaults not KDE.

Though I will agree that KDE is a bit harsh, even on my very well equipped almost 3-year old system, but that seems more CPU/GPU-related than RAM-related. And it's not like it causes huge issues, just a bit of sluggishness, which is not a total dealbreaker for most people.

I run KDE on my 3 Linux virtual machines. The host has a Ryzen 5700G and 64GB of RAM. Each Linux machine has 8GB of RAM. Each machine is snappy - they're never sluggish. Your sluggishness is not due to KDE.

Not true for plasma, they do a awful job building it. They just don't follow the best practices for Qt and plasma, it is a secondary class software for them. For plasma user in any other distro the difference is visible from the first login. If you want a out of the box, upstream plasma experience, there is just one way, neon

Dear Linux not-fan, would you be so kind as to stop "striking again" yourself, as your presence, flamebaits and incessant plugs of your retаrded website are not appreciated by pretty much any visitor of this forum?

Do you feel the same way about users that post insults and flamebait towards Windows users, or the posters that rag on Gnome or Ubuntu or Intel or NVIDIA?

People have different opinions and see things differently than others, we either have free speech or we don't have free speech.

You have no problem posting dumb stuff, should you be held to the same standard.

How about growing up?

Don't reply, no discussion necessary.

Aren't you using a custom compiled kernel?

Your experience is not indicative of what an average user will see with a default install of Fedora 41.

Not to mention that you donate 20 Euros to KDE every 6 months so they probably supplied you with an optimized version of Plasma.
