Why does ubuntu slow down after a few hours of work?

Question

linux

Greetings.

I have ubuntu 20.04 on my work machine and laptop. The problem is on all two PCs.

After several hours of work, the system interface starts to slow down. Open the calendar on the top panel, open a folder on the desktop - everything is accompanied by micro brakes for 1 - 2 seconds.

The program interface itself (chrome, editor, etc.) does not slow down. Friezes are precisely when interacting with the gnome-interface, if I may say so :)
The system monitor does not seem to show processes that could somehow load the system.

I can't figure out what could be the problem. I reboot the system, after a few hours of work - everything repeats.

Answer 1

The symptoms seem to indicate that parts of gnome have been pushed into the swap file (can be checked with smem) and are accessing the disk when invoked. If so, then I would try zswap.

Answer 2

Computers are dead.

Answer 3

Switch to Kubuntu, Gnome is no longer a cake. It has more RAM and fewer features than in KDE.

Answer 4

Memory is probably leaking, but nothing can be said without logs.

Answer 5

Maybe half of the processor power is being eaten up by the tracker-store file and folder indexing service?
