Ok, system may be merely overloaded, but in this case expected that user experience should not getting worse. Switching between tasks (showing activities in gnome shell) should be such fast as after reboot in ideal. I am understand that is not easy and depends at many factors. But I notice that every new Linux release working better also at overloaded case. And it's very nice. So if five year ago using swap was impossible because system was becoming fully unresponsible. At now I see freezes not not exceeding 10 seconds. I hopes thats working on this warning messages can make Linux better. > Your system is hosting a lot of > processes including QEMU and Chrome on 8 CPUs + 32GB RAM + 64GB swap and > nearly a half of swap is in use, isn't it?

Don't hesitate trouble me in further. I am wonder to know what else tracepoint needed enable for deeper debugging.
