Currently when profiling we have no easy way to answer the following question: - Did one display item dominate the cost or was the cost eventually distributed. - How much time does this section of my page take to paint. - What part of the page was responsible for this large paint. We can sometimes answer the above but only if you can trivialize the problem. For example on task.js which has a large gradient background we spend a lot of time in PaintGradient. However in general it's very difficult to infer this. By annotating the stack with the active display item and dumping the display list we can answer the above costs.
