I don't believe it's only chrome's problem. I've noticed that firefox tends to lock all available memory to himself and whenever I need it, bastard just reallocates it into swap, making whole system laggy and slow.
So.... I've got my foxy friend into a Ram jail for being too hungry:
systemd-run --scope -p MemoryMax=1G --user firefox
God, I love linux!
mod+shift+q
so you wouldn't close hours of work by accident (e.g. when typing othermod+_
keybinds)
