x server - FreeBSD

Why does x server always use a avarage of 1% cpu time while i am doing nothing ? Everything els is 0% except x and enlightenment ?...

    If I would have my TV viewer running (kmplayer) and do nothing for an extended
    period of time I bet it would show a lot more cpu than 1% still.

    Same with websites that use heavy and/or broken javascripts or flash. Can yank
    up cpu easily even for common tasks. I have a brand new oven (thats an intel
    mobo with a 3.4 GHz processor) and it gets a lot more noisy (fans spinning
    faster) when making world (in 35 minutes) or playing a dvd or a low bandwidth
    encoded mediastream in (k)mplayer. Anything that makes the cpu really have to
    work.

    Besides, the optimal cpu time used for any process is 100% as they all compete
    for cpu bandwidth (if the system would be under duress). So basically your
    system is doing great and is not overloaded at all. It's gravely underused
    one might argue ;-)

    What is the difference between a console and a xserver ? My console is
    always 0% and it has a mouse too just as the xserver showing the same
    thing ?

    Any process needing CPU, that is. Unix tasks are encouraged to block when
    they don't have any work to do-- this is very common when a process is reading
    data from a pipe or socket.
