Re: question about cpu usage

All these talks about why CPU usages should be
below 100% would make an experienced Mainframe
system programmer -that is an syste administrator
in unixspeach for self-respecting system administrator
*do* write programs in assembly- smile. Everyone knows that a system
need to be at 100% CPU usage or
otherwise the system is underutilized. 

The reason why UNIX administrator loses his temper
when CPU utilisation goes beyond 60% is that UNIX
monitoring tools do not count pure CPU usage. They 
add system time, time spent in I/O and everything 
else in the count. UNIX task chedulers are so lame
that they can not properly distribute CPU time 
between interactive processes wen load average 
goes beyond %60.
