I would like to see a similar comparison, but for the latency of completing various actions, like startup time, switching windows, opening the launcher menu, navigating to a subdirectory... These are the things that matter to me - much moreso than RAM usage. My informal anecdotal experience is that XFCE latency is nearly always imperceptible, whereas GNOME latency is nearly always perceptible.
