Phoronix: GNOME 3.26: Wayland vs. X.Org Performance - Boot Times, Power Use, Memory Use & Gaming

While testing out the near-final GNOME 3.26 this weekend I also ran some benchmarks of it comparing the boot time, memory use, power consumption, and gaming performance when comparing GNOME Shell / Mutter running on Wayland and then an X.Org session.

I would have been interesting to see how Wayland effects gaming speed on AMD (and Nvidia when you can actually use it) also

gnome supports EGLStreams so you should be able to use nvidia with gnome wayland

NVIDIA drivers don't support XWayland though. All games work under X as of right now.

Appart from not being able to launch software like gprated (and anything else relying on running with root privileges), gnome-shell running on wayland seems fine to me during normal, daily usage.

Some don't need X, Xonotic for example.

As was mentioned in other articles by many users here, yes, you can run gparted et al. in Wayland sessions.

Here is a nice piece of code by Veerappan :

  
[FONT=arial]#!/bin/sh

[ -n "$@" ] || exit 0
xhost si:localuser:root
sudo $@
xhost -si:localuser:root[/FONT]

All you would need to do after is call this script with an alias (say "sugo"), and then run gparted: sugo gparted.

I'm aware of this workaround, but thanks for pointing this out anyway. I was just giving my thoughts about gnome-shell running in a wayland session from a "regular user's" point of view.

My brief experience with Wayland, although on Ubuntu-GNOME 17.04 with gnome-shell 3.24:
- Wayland has increased input-lag, very obvious during mouse movements
- Sometimes the mouse pointer freezes, or doesn't follow the mouse movements for a second or so
- Looks like I'm getting only 60 frames per second despite running my monitor at 120hz, judging by how the mouse pointer moves
- Most official GNOME apps work fine, but third party apps do not always work as expected
- Steam and games seem to work fine for the most part, but there are issues with increased input lag and it does look like not all rendered frames actually reach my monitor, becouse it subjectively stutters more than X but the frame-rate counter shows the exact same numbers as under X.

I will most likely install Ubuntu 17.10 when it officially releases. I'll give Wayland another shot, but I suspect I will switch back to X and hope it's ready for 18.04.

Edit:
I also have an old laptop which is running Arch with gnome-shell 3.24, and Wayland is default there, but I've actually changed it to X becouse it has Nvidia graphics and there was a few apps that didn't work as expected. My desktop is an AMD build with Ryzen R7 1700X, R9 Fury and open source graphics drivers. Oh, and did I mention VDPAU doesn't work on Wayland? That's a pretty big deal to me, especially on the laptop.

The numbers don't convince.

There, I've said it. Now flame me.
