Results

It's really hard to compare paint-performance in general. (Mostly just visual) For now I only tested in Chrome, as it is the only browser which allows you to track this kind of information. Still, to get universal results is almost impossible as the performance depends on so many factors. My results can roughly be summarized as the following (take these results with caution):

Chrome 32.0.1700.72 beta
