[Wayland] Slow frames

Open HidenoriMatsubayashi opened this issue 3 years ago • 6 comments

Obviously slow frames are more easily occurring with Wayland backend compared to X11 backend. Bottleneck is eglSwapBuffers and it takes about 18msec every frame.

@HidenoriMatsubayashi , I am testing flutter-elinux on ARM64 (imx8) platform, on wayland (drm-backend) , found the gpu and cpu utilisations are high for flutter-applications, would like to know how to do better gpu profiling for flutter-elinux ? if this thread is not for gpu, please suggest me the right link,

I think BSP vendors usually provide the GPU profiling tools. I recommend you use it to analyze GPU performance. Whereas, if you want to analyze flutter apps performance or this embedder, you can use DevTools.

@HidenoriMatsubayashi , thank you for the inputs, sure will try devTools as well, but do we need to take any special care to enable GPU support while building flutter ?

Nagendra-Bankupalli avatar Dec 10 '21 04:12 Nagendra-Bankupalli

Yes, but can you check whether GPU is enabled in your target platform using some tools like glmark2?

glmark2-es-wayland works fine on my HW!

@HidenoriMatsubayashi On my platform glmark2-es-wayland works well, but flutter gallery app is slow, what could be the issue?

What device or board are you using?

HidenoriMatsubayashi avatar Oct 12 '22 12:10 HidenoriMatsubayashi

its ARM64 based system

B-Nagendra avatar Oct 12 '22 12:10 B-Nagendra

Specifically?

HidenoriMatsubayashi avatar Oct 12 '22 12:10 HidenoriMatsubayashi

its custom hw, its TI based (PowerVR + openGLES 3.1), powrVR supprted in flutter 2.5.0 onwards , (not sure about flutter-elinux) my flutter-elinux version is Flutter 3.3.3 • channel unknown • unknown source Framework • revision 18a827f393 (2 weeks ago) • 2022-09-28 10:03:14 -0700 Engine • revision 5c984c26eb Tools • Dart 2.18.2 • DevTools 2.15.0

Thanks for sharing. Are you using release mode? Can you please share the score of glmark2-es2?

HidenoriMatsubayashi avatar Oct 12 '22 12:10 HidenoriMatsubayashi

release version is better,still not good , glmark score is 114

B-Nagendra avatar Oct 12 '22 12:10 B-Nagendra

glmark score is 114

It's too low... Is GPU HW accelerator enabled?

HidenoriMatsubayashi avatar Oct 12 '22 13:10 HidenoriMatsubayashi

yes, will check why the score is low, thank you
