From the "Similar Efforts" section toward the bottom:
---
David Ramiro built his m2p-latency and compared X11 vs Wayland in his article Building an Input Latency Meter (Because ‘Wayland Feels Off’ Isn’t a Metric) as well, coming to similar conclusions:
Native Wayland is on par with native X11 (all tied at ~7 ms), while XWayland roughly doubled the latency in his tests.
farnoy did extensive testing with the Open-Source-LDAT in his post Linux latency measurements and compositor tuning, also concluding that XWayland should be avoided.
