Every developer has an opinion on X11 vs Wayland. Almost none of them have measured it.

Bt someone actually did. They ran controlled benchmarks across multiple setups and found that X11 beats Wayland by 0.14 to 0.22 milliseconds. That is smaller than the margin of error in most human perception studies.

So why does Wayland still feel worse to some people?

XWayland. Running an X11 app through the compatibility layer adds 3.13ms of latency on its own, more than every other factor in the test combined. If you are blaming Wayland for feeling sluggish and you are actually running XWayland apps, you are blaming the wrong thing.

The single biggest win in the benchmark was enabling VRR. Variable Refresh Rate reduced latency by up to 0.45ms and, more importantly, made frame delivery dramatically more consistent.

The takeaway: the display server war is basically settled on performance. Native Wayland apps are fast. XWayland is the bottleneck. VRR is the upgrade worth making.

I like both them , like coffe and tea.
