[Bug 1225985] Re: gnome-shell uses over 300% CPU most the time
Lets rule out memory related issues first. Would you post the output of free during one of the times that you are having this problem. It's quite possible that this is due to either SWAP being disabled, or having too small a SWAP partition. I've also done some poking around with different versions of chromium, and in the last few releases, Google Chrome Renderer acts up in combination with flash, and I haven't seen a patch for that particular issue come over here yet. A patch exists, but hasn't come up for consideration in chromium yet as far as I can see. If we can connect this issue to that bug, I will propose integrating the aforementioned patch into the next stable upstream release so that it should get integrated down here as well.

Nothing in the logs provided has any hints as to why gnome-shell is that much of a resource hog. If you wouldn't mind posting your hardware specs, that would be helpful in any attempts to reproduce the issue. There aren't any leaks as far as I can see in either the mainline or proposed builds of gnome-shell.

The other helpful upload to have would be a valgrind log. Follow the instructions here https://wiki.ubuntu.com/Valgrind. This will detect any memory issues, which as the gnome-session logs didn't show any glaring issues, is what I'm leaning towards calling this. The valgrind log will give me a clearer idea of how to proceed, and I will let you know what the next steps will be.
