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, James Jones Northeastern University College of Engineering Boston, Massachusetts 02115 (617)437-4430 CSnet address: JAMES@VAXE.COE.NORTHEASTERN.EDU
