Yeah I noticed too; gnome-shell is surprisingly inefficient. The good news is that v3.25 aims to make things more efficient, so that's something to look forward to.
Just a note: The exact CPU usage will depend on your CPU model and what apps you're running (not just the Gnome version). I experience 20%+ CPU usage by gnome-shell on a high-end Xeon desktop, just while it's redrawing the screen, which is surprisingly bad. But it will take some time before the upstream optimizations trickle into Ubuntu, and before I have time to look at more detailed optimizations in future. ** Tags added: performance -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in 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 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
