Of course, notice that the Xterm (or worse, kterm etc.) you're running
the top command in _is_ flooding the X server... :-)
(I've actually measured this some ten years ago -- the result (on *that*
old system, your mileage will be totally different I'm sure) was that
top+xterm took 10%-20% cpu. top itself *still* takes ~2% cpu on busy
systems (lots of processes), and the Xterm situation has not considerably
improved either, I feel confident in saying).
