Gnome Shell Random Excessive Slowness!
I experience a random slowness of gnome that requires restarting the shell. There is no known way to trigger it. It just happens in random. Closing all running application does not resolve it, thus pointing to gnome shell as the prime CULPRIT of the slowness.
This is the profiling information i could get during that time:
