Phoronix: GNOME Shell Wayland Benchmarks From Fedora 20
While an X.Org Server is still used by default on Fedora 20 "Heisenbug", Wayland has become a viable option for early adopters and developers wishing to work on Wayland software compatibility and/or testing. All the packages are needed on a Fedora 20 installation to launch a GNOME Wayland session and begin working, including support for XWayland in order to run X11-dependent games and applications.
Pretty much everything in this benchmark is effectively testing the overhead of using XWayland, rather than anything to do with Gnome Shell. And that might be reflective of how things work for the time being, but are there any benchmarks that can usefully compare Gnome-on-X with Gnome-on-Wayland, without the bottleneck of XWayland?
Further study necessary, but interesting none the less.
Back on topic...as was mentioned in the first comment, these benchmarks almost all test purely xwayland against X11. It'd be nice to see some benchmarks without any X-shims, wayland or mir, though I understand that X-less benchmarks are rare at the moment.
