Ramdomly high IO activity when watching video

more options

It usually happens when I loading page or watching video on YouTube/ Bahamut Anime(ani.gamer.com.tw). When it occurs, the video still can play until the video cache empty, and after switching to another and switching back, the page becomes all white except a loading circle at the center. This situation takes about 3~5 minutes. I have tried refresh firefox, and disable all addons.
