After profiling it, it looks like most of the time spend scrolling is spend inside
RenderBox::mapLocalToContainer  and RenderLayer::convertToLayerCoords.

RenderBox::mapLocalToContainer is called indirectly RenderLayer::computeRepaintRects.

RenderLayer::convertToLayerCoords is called from several places.
