Hi Brooks,

Thanks for responding...

However I'm confused by the terms used.  Are you saying if I set it to 0, I
would be using the processing power of all CPU's?  I'm not sure how this
halted comes in to play, cuz the only thing that comes to mind is to halt
the machine as in shutdown....  I'm probably confusing terms here... can you
expand and clarify?  I just want to make sure what this all means.  Also is
this an option that can be modified via sysctl -w and the /etc/sysctl.conf
file ?  Or is this going to have to be set in a boot option?
