AFAIK, gnome-system-monitor is one of those rare apps which are software
rendered (because GTK) but also try to animate at a smooth frame rate.

It's a rare combination and a useful test case.

If I run eclipse from a docker container (with -v /tmp/.X11-unix:/tmp/.X11-unix 
), then no cpu overuse.
It might related to that in this case eclipse cannot connect to dbus.

Thanks. That explains a lot. I think gnome-shell is presently too slow
to be able to handle 1080p on a Celeron 847. But we are working on a
bunch of different optimizations that should help in future.

Nevermind, it's obvious you're using Xorg sessions.

At what resolution though? Please just run 'xrandr' and send us the

2018-05-27 Thread Daniel van Vugt
Oooh... that makes sense now, thanks.

The problem you are seeing is with mutter/gnome-shell being inefficient
at frequently-updating software rendered windows. This is a known
problem, but until now we only knew of Eclipse triggering it (bug
1756508), and the older pre-Quantum versions of Firefox (bug 1696305).

What you are seeing is a known performance problem, but you have
discovered a great test case for it in the Resources tab. So thanks.

As I suspected, this is not a problem with the new Firefox at all (which
is hardware rendered). It's a problem with gnome-system-monitor, or any
frequently-redrawing software rendered (e.g. Gnome) app.

I only have two more questions: What is your display resolution, and are
you using Wayland or Xorg? Both of these can be answered by running
'xrandr' and sending us the output.

2018-05-26 Thread Yuri
I restarted my computer 3 time.I launched FF and the top command. The home page 
of FF is https://www.bing.com/?cc=be. I opened a second tab with 
maps.google.com. Everything was find. I lauched system monitor and then, the 
CPU of one core jumped to 100 %, even after closing the maps.google.com tab 
(see screenshot).
When I'm in system monitor, the tab Ressources take 100 % of 1 CPU. If I switch 
to the tab Processes and change the ordering of the list, it goes down. When I 
come back to the Ressources tab, it reaches again the top. Same thing if I go 
from the Ressources view to the File System tab and back to the Resources tab 
(see screenshot from 11:50 AM).

OK. Please reduce the problem down to a single app, like just Firefox. Now, 
please let us know:
  1. The version of Firefox; and
  2. What web page(s) cause the biggest problem.

I think my list of planned fixes for Ubuntu 18.10 [1] will be the best
avenue for helping you because the Celeron 847 has a passmark [2] of
936, and I estimate gnome-shell presently requires a CPU with passmark
around 5000 or more to run smoothly. Obviously we need to get that
number down a lot by optimizing gnome-shell in future...

The CPU seems taken by Xorg (see screen shot). When the gnome-shell proc
take most of the CPU, the overall CPU seems to be reduced after some
