Concentrate either on the pair of videos at the top: - Ubuntu defaults vs openSUSE with nosmt=force, spectre_v2=retpoline and energy_performance_preference set to balance_performance. or the pair of videos at the bottom: - Ubuntu defaults vs openSUSE defaults In both pairs of the videos, the overview button is pressed at the same time on both machines. That means that not only performance/smoothness is shown, but also the lag ie when there's visible action on the screen. This mainly just confirms that a) performance with defaults is very bad, quite unusable, b) performance with known tweaks is better, but still far worse than it should be. -- You are receiving this mail because: You are on the CC list for the bug.
