	The only reason that an 8600 will slow down is because
	the 8600 is the only VAX that can push say an RA81 to its
	performance limit.

	Even an 8600 does not use up the entire unibus bandwidth. We found
	that our 8600 was on its knees (running VMS) because of a job with 
	extremely high paging rate. It actually was due to an RA81 
	(there was only one disk at that time) becoming a bottleneck, 
	NOT the unibus.
