Hi,
	I heard a rumour from a person I know at DEC concerning what is the
best base priority for a VMS system.  Normally, most systems seems to have
4 as the base priority for interactive and batch jobs, with batch jobs being
lowered depending on the system load.  The person I spoke to mentioned hearing
that the best base priority is 5 rather than 4.  He spoke of the algorithm used
by the swapper (I believe it was the swapper that he referred to) being made 
more efficent by using 5 rather than 4.  Has anyone heard about this?  Does it
make sense to do this?

	In a related subject, how about a setup with interactive jobs at 4 
(or whatever the base priority is) and batch jobs at 1 less than the interactive
jobs? Will this improve or degrade system performance?

Thanks in advance for any replys,
