3/21    If a user were to leave top running on a system perpetually, would
        that cause a constant, appreciable performance hit (this is actually
        happening on an ultra1, and the user is an admin, not at ucb)
        \_ Not really.  -tom
        \_ On older machines, top would take 20% or more cpu time.  It still
           isn't any more efficient now.  A faster/modern machine will have
           more cycles to kick around on this.  I suggest using top to see
           how much load top requires on that host.
        \_ Why would you want to run top all the time anyway?
                \_ Because the sysadmin is too stupid to figure out how to use
                   SNMP, sar, or a million other less intrusive tools to track
                   system resource usage.
                        \_ whereis sar? (what is it too?)
                                \_ /usr/sbin on Solaris.  See the Sun
                                   Performance Tuning book by Cockcroft for
                                   more info.
