Which has lower latency… Wayland or X11 (Xorg / XLibre)?

Wayland developers and advocates have claimed, for many years, that Wayland is faster (with lower latency) and more efficient than X11.

Nvidia has conducted research into that question… and determined that…

Wayland does NOT provide lower latency than existing X11 servers.

This shows that Wayland has failed at one of its core goals (to remove architectural “bottlenecks”, providing improved performance over X11)… a goal which Wayland has been working on for over 18 years without success.

In other words:

- Wayland uses more RAM than X11.

- Wayland is missing significant features of X11.

- Wayland is no faster than X11.

It will be interesting to see how Wayland advocates spin this.
