So - here are the quite interesting results of my benchmarking yesterday:
At first I have to apologize : I wasn't able to reproduce the very high score of my last post :
I use the tiling plugin of Wayfire with added padding, so the render-window of glmark2 seems to have been scaled down or cut off. I guess, that explains the ~10% difference to the last result.
So the benchmark was made with floating windows on Wayfire, without wallpaper on both DE's, and additionally I turned tracker off on GNOME3 - otherwise that would have been an unfair comparision, I guess.
The benchmarks were executed in series on each DE on the same user-account by an script and the stout piped to the files containing the results.
As an suprising summary GNOME/Mutter performed through the line considerably better than Wayfire on the glmark-wayland benchmarks, but nearly failed on the other benchmarks.
- that doesn't reflect the user experience in ANY WAY
I invite everyone to test this out: GNOME's rendering of GTK3, the font-rendering and even the wallpaper looks awful
in relation to Wayfire. There are artifacts here and there, The whole desktop feels sluggy input-wise and all effects are lagging. Not that GNOME isn't useable on the Odroid-N2 with my system, but the difference in response time's and rendering quality is so
evident in relation to Wayfire that the numerical benchmark results have wonderstrucked me...
I hope this results are of use for someone here, and if the community is interested, I would update the results when something relevant happens to my setup with the coming updates - now, that I have the scripts and the Templates. If someone is interested in the results of other Kernels or anything else, I could help out as long as I have GNOME installed. So you shouldn't hesitate to ask for soon.
EDIT: The result also shows that performance-governor doesn't provide any big advantages anymore as @chewitt stated, although it appears to me, that WebGL- Aquarium and Dynamic Cubemap are performing a little bit more fluent with it.
2nd EDIT: GNOME's performance seems to suffer remarkably more than Wayfire by simple_ondemand governor...
