Comment #54 on issue 5083 by windinyews: High browser process CPU usage from Flash on Vista http://code.google.com/p/chromium/issues/detail?id=5083
gwilson, this is a real and very unfortunate problem, and I am just amazed that Google engineering isn't to the bottom of it. I moved recently to a 2-core 2 GHz laptop, which is very spritely at everything including 3d rendering. However, it cannot run even one tab in Chrome that has Flash in it, without heading immediately for trouble. I simply can't use Chrome when on batteries: it cuts the life in half, from 4 hours to less than 2. Yes, recent versions of Chrome tend to bound the damage, holding down peak CPU usage to keep some reserve. However, Firefox can run any number of the same windows without any appreciable CPU loading. The simple experiment for you: load up a bunch of tabs from the New York Times (nytimes.com), chosen off the Most Popular lists, where the ads tend to have motion, and especially those ridiculous animated patterns from IBM. My suspicion is that your real problem with Chrome is the sandboxed task-per- tab/window model, where you have not implemented any interprocess communication to stop Flash engines running in non-visible tabs/windows. Is it any more complicated than that, or any more trouble to admit to and fix? In a mobile world, we can't afford to be plugged in just to run Chrome. Other than this problem, it is a wonderful, agile browser, and so nicely attuned to your products. I think you see what you need to do. I really would encourage you not to stone-wall on problems like this in the future, as well, and I'm sure you actually can understand the reasons to say so, at Google.
