Cog: How to check if the GPU is really being used for hardware acceleration?

[Oquirella]

I get really poor performance on pages where svg graphs are being used. (on IMX8MP with vivante graphics driver).

[psaavedra]

SVG is being integrated in the accelerated graphics pipeline nowadays (ref: https://bugs.webkit.org/show_bug.cgi?id=90738) on WPE WebKit. @nikolaszimmermann is actively working on it.

I have added the option to wpewebkit.inc:

PACKAGECONFIG[svg] = "-DENABLE_LAYER_BASED_SVG_ENGINE=ON, -DENABLE_LAYER_BASED_SVG_ENGINE=OFF,"

I will start the build now, if it is performant, we should enable it as default.

[nikolaszimmermann]

I would call the option „lbse“.

I enable the option, but i didn't see any performance improvements when showing my SVG graphs @nikolaszimmermann. The library i am using is: https://github.com/amcharts/amcharts4

Huh apparently I deleted the lower part of my answer. LBSE is under active development - it is neither built by default yet nor activated at runtime. You won‘t see anything by just compiling it in… you will have to wait before you can test it (probably in Q4).

[Oquirella]

That's too bad @nikolaszimmermann , i really wanted to test this feature. Is there no nightly or experimental branch or patch where this feature is fully enabled?

[nikolaszimmermann]

No not yet, we're working on it to make it happen soon.

[Oquirella]

The performance on the svg graphs in chromium is so much better, with cog it is unusable...

[nikolaszimmermann]

We're aware of the current limitations and actively work on improvments. If you want want to assist and getting your specific case to work faster, a striped down minimal reduced version of your web page, which exhibits the performance problems, would be helpful.

My website uses something like this: https://www.amcharts.com/demos/live-data/ https://www.amcharts.com/demos-v4/live-data-v4/
