Sorry I'm totally newbie here and with ubuntu, but I regularly face the same
problem with Ubuntu 17,10 in Virtualbox, when I run eclipse:
Version: Oxygen.2 Release (4.7.2)
Build id: 20171218-0600
Either this happens at startup of Eclipse, or after a while with no obvious
reason...
Seems this is
This bug is affecting me as well. I just ran `ubuntu-bug gnome-shell`,
hopefully you can see my files?

Rasmus: I think other people have reported performance problems with the
Activities overview already. Maybe you should join bug 1698792 to
discuss that one. I think upstream Gnome bugzilla has reports of it too.
Let's keep this one about gnome-shell's CPU usage while Firefox is
running.
It's impo
The above bug seems to be solved or at least mitigated a bit. With just
having firefox up the CPU usage of gnome-shell is between 2-5%.
Gnome shell is still much less performant than Unity though, by moving
windows, open Activities or dragging the mouse over the dock its CPU
usage quickly jumps to
This bug is probably a bit out of date now. I don't see problems as bad
any more.
Rasmus: Please test again with the latest firefox (I think the newer
versions ~57 or so are much more efficient). And if you can, also test

Everyone else:
I think this bug is about the single monitor case. Please open a new bug
for the multi-monitor case.

I also experienced increases load on my laptop with an external monitor
in addition to the built-in screen. The load is low initially, then
increases such that the fan turns on. Disconnecting the extra monitor
reduced the load 30s after unplugging for me.

High CPU usage in gnome-shell just redrawing the screen
It affects me too.
I'm on Ubuntu 17.10. Closing all apps but System Monitor, then moving
the mouse up and down on the icons in Dock bar, keeping on, and my
i7-8700k will be rapidly consumed 80+% even 90+%.

Title:
High CPU usage in gnome
It appears the high CPU of gnome-shell with totem on Wayland at least is
due to the totem app window redrawing at 60Hz seemingly only on Wayland
(bug 1698282). When this happens, the compositor will have to upload
(copy) the window texture from CPU to GPU 60 times per second, which is
CPU-intensive

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%

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 experien
Also note:
Xwayland is using high CPU because you're running Firefox.
Firefox is using high CPU because, well, it's Firefox.
So you can ignore those two.
