Yes indeed. We have a few bugs tracking those problems:
https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bugs?field.tag=performance
But I was going to wait and see how the optimizations in Gnome 3.25/3.26
work out before worrying about them.

Hi,
I have been trying gnome-shell on artful and the performance of shell is
pretty poor compare to Unity.
By performance in general I mean:
a) jittery animations
b) lag when moving windows
c) high cpu usge
d) high memory usage (gnome-shell process)
e) overall smoothness
Here is the result I gather so far (without any third-party extensions):
1) Dell XPS 13
X: Somewhat works ok
Wayland: Lags with animation
2) i5, Nvidia 940/965, 8 GB RAM
X: Lags everywhere even with animation disabled
Wayland: Lags everywhere even with animation disabled
Cpu: High, Memory: high (> 400 MB)
No games on wayland
3) i3, intel hd 5500, 4400, 8 GB RAM
X: Lags everywhere with animation disabled + screen flickering
Wayland: Lags even more than x (but no screen flickering)
Cpu: High, Memory: high (> 400 MB)
No games on wayland
4) Core 2 Due (Quad Core), intel 965, 4 GB RAM
X: Not usable
Wayland: Doesn't boot
It has been like this since the beginning with mutter....Finally
upstream making an effort to improve
performance : https://bugzilla.gnome.org/show_bug.cgi?id=782344
It's huge change with ABI break and may land in 3.26, that is why I am
thinking may be
it's not a bad idea to stay on gnome-shell (3.24) for 17.10 (even with
this poor performance).
Thanks.
