/glmark2/bin/glmark2-es2-wayland
[build] use-vbo=false: FPS: 31 FrameTime: 32.258 ms
[build] use-vbo=true: FPS: 31 FrameTime: 32.258 ms

Yeah, this has been annoying me too. You need to set repaint-window=15 in the [core] section of weston.ini. Either all repaints really do take that long, or there's a bug in the KMS driver timings. I've only seen this on Rockchip, not other hardware.

Cool! repaint-window=15 works.

now glmark2-es2-wayland become 60fps.

Thanks Daniel.
