This has long lists of chained filters. Is Firefox performance significantly different to any other filter supporting UA?

Comment 2

[ferongr]

Chromium exhibits no visible slowness and hovering over the different circle segments produces a visible result nearly instantaneously.

Against current Trunk the Profile of Comment 0 is still valid with

Selection - Most time spent in:
    nsSVGFETurbulenceElement::Noise2(int,double * const,nsSVGFETurbulenceElement::StitchInfo *)
    nsSVGFETurbulenceElement::Noise2(int,double * const,nsSVGFETurbulenceElement::StitchInfo *)
    nsSVGFETurbulenceElement::Turbulence(int,double *,double,double,int,bool,bool,double,double,double,double)
    nsSVGFETurbulenceElement::Filter(nsSVGFilterInstance *,nsTArray<nsSVGFE::Image const *> const &,nsSVGFE::Image const *,nsIntRect const &)
    nsSVGFilterInstance::Render(gfxASurface * *)
    nsSVGFilterFrame::PaintFilteredFrame(nsRenderingContext *,nsIFrame *,nsSVGFilterPaintCallback *,nsRect const *)
    nsSVGIntegrationUtils::PaintFramesWithEffects(nsRenderingContext *,nsIFrame *,nsRect const &,nsDisplayListBuilder *,mozilla::layers::LayerManager *)
    mozilla::PaintInactiveLayer
    mozilla::FrameLayerBuilder::DrawThebesLayer(mozilla::layers::ThebesLayer *,gfxContext *,nsIntRegion const &,nsIntRegion const &,void *)
    gfx::DrawThebesLayer

As an Addition since SVG Display List's Landing this is now even more worse CPU Usage-wise during Onload as you can see when you disable their Prefs and compare.

With the latest perf gains related to reflow and invalidation, I'm now seeing 95% of the profile time under nsSVGFilterFrame::PaintFilteredFrame.

Comment 5

[Markus Stange [:mstange]]

This is much better with the new filters. Hovering over the percentages on the right is near-instant. Hovering over pie chart segments doesn't do anything for some reason, but that's unrelated to filter performance.

Site seems to be gone now I'm afraid.
