Any tips on determining what exactly is happening in a frame that causes it to render so slowly? Paul Irish and Paul Lewis touch this topic briefly here . According to this video, white bar indicates browser waiting for a CPU or a GPU and there is nothing that developer can do to fix this (assuming that he is working on
