Opening the browser with 5 open tabs starts to freeze, it gets worse if another program is open. Yesterday I was watching a movie (VLC) and the system was slow, as in the games when the fps is below 30.
I formatted the pc and installed the Manjaro Deepin, greatly improved the performance. Deepin should focus 75% on improving performance, so it would not lose users.
