On a related tuning question: I (foolishly) decided I'd help out our system administrators in setting ANU-NEWS up. In using it for the first couple of months (We did get it to work fairly easily) we suddenly found that my bills for use of the computer system skyrocketed. Yes, thats right, my VAX time costs money. The overriding cost increase was caused by excess page faulting which started with the advent of our news feed. So how does one optimize for expenses which are calculated by this formula: CPU Time (Day) $1.26/min CPU Time (Night) $0.04/min Page Faults (Day) $0.10/1000 Page Faults (Night) free Buffered IO Ops $0.03/1000 Night is generally very late, and I have problems running this with my 1200 bit/sec modem so... Has anyone done any work with this? By the way, as a knee jerk response I twisted the arm of one poor system operator to increase my working set size from 1028 to 4096 (I'm not an expert - what units?) and am hoping that this will help somewhat. And what causes the page faults? If working set size is the solution, how can it be increased only when running news?
