Chromium CPU usage high with Pepper Flash

[Christopher Forster]

Hi, Chromium used too much CPU usage with Pepper Flash. I don't know if the Pepper API has really had time to be tested in the real world? New technology may sometimes cause problems, consume more resources until extensive rigorous testing & until fine-tuning for the performance. I found Chromium had higher CPU usage than normal when playing an online game using Pepper Flash.
