Layout Utils::View IDFor ASR is relatively expensive
59 bytes, text/x-review-board-request
I profiled the new clipping code and 16.8% of the time in it is spent in nsINode::GetProperty(). I believe these mostly come from nsLayoutUtils::ViewIDForASR. The clipping code is only about 10% of our WR display list building time now so fixing this is not urgent. But it's probably the first low hanging fruit in this area to look at when we get the chance.
