Re: Restrict jobs CPU usage

[John Hall <jhall@xxxxxxxxxxx>]

This seems to be a common misconception among the midrange community.  I
have run into programmers who describe programs as "dogs" solely because
they use 100% of the CPU time.  This has nothing to do with whether the
program is good or not.  It merely reflects that the system is well
tuned to performing this task and that the Job does not have to wait for
resources to become available.  The amount of resources that a program
uses to accomplish a task (CPU, Disk IO etc.) is an entirely different
matter. 
In the Vax/VMS environment that I used to program in the goal was to get
as close to 100% CPU Utilization as possible.  Of course at the same
time you wanted the minimum amount of CPU time to be used.
