Comment 21 for bug 1973434

I also have Performance issues, so i managed to get pattern on my machine.
I have a Rycen 5, 32GB Ram and a Nvidia card.

i had 20.04 it was fine, then i did a fresh install for 22.04.
The first 2 days or so i had no trouble, yes it runs a bit laggy but i was fine with it, then i played a game. It was horrible, after closing my browser the game runs fine.
So i startet to search for something, maybe my RAM runs full? Check no it hit 17GB out of 32, so at exactly 17GB it starts to go crazy, CPU usage is ok, some go to like 60% max but it laggs all over the place. I had no CPU usage spike over say 70% on working and/or gaming.
I dont know how to see my GPU usage.

I also can rebuild the youtube Tab lag, after like 12 GB of RAM usage it goes slower, but not much.
I stoped this test at 20GB, i hat a max CPU usage of 84% and ~78% on the rest of the cores.
So, only on my web browser its fine to go to 12GB, at 17GB ist bad at 20GB its the same as 17GB, But a playing a game and the web browser at the same time at 17GB its realy bad.
I dont know maybe someone can work with this informations.
