Thanks for you info. I thought my M.O is utilizing it after I have installing it.
I also try to find out using the demo sets from Apple reseller store
Those units don't have this windowserver utilizing

hmm, I should put it better in this way.
windowserver is responsible for communicating with every program to display the content on your screen (Microsoft office, safari, Dock, Desktop, top bar, etc.)
it handles all the task of rendering and cache all the visual stuff (app, websites , windows, etc.), so if let's say microsoft office's window or safari webpage has something that require frequent visual updates/processing, it will take a lot of cpu and memory
probably those demo unit doesn't have much running on them, so the windowserver don't show up at the top? unless you specifically search for the process in Activity Monitor
