Note gnome-shell's performance problems relate to redrawing the screen (ie. when anything on screen is changing).
For example: CPU usage playing Big Buck Bunny 1080p 60FPS: Unity7/Xorg (fullscreen) totem 80% compiz 4% Xorg 5% Unity7/Xorg (windowed) totem 80% compiz 6% Xorg 4% Gnome/Wayland (fullscreen) totem 120% gnome-shell 40% Gnome/Wayland (windowed) totem 120% gnome-shell 40% You can ignore 'totem' - its performance is different probably because the Wayland code path is not yet as efficient as the Xorg one. The relevant point is that gnome-shell uses 4x the CPU of Xorg+compiz to draw the same thing... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1696305 Title: High CPU usage in gnome-shell To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1696305/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
