I was the only person logged in, the load average was straight 0's. The machine has 24MB, and provides NFS service to a handful of systems, none of which are currently active. I got 35 dps again. >}DEC 2100 4.0 13 Light > DEC 2100 3.1d 22 Very Light I ran this again, too. This is my personal machine. It has 16MB, no other users. I'm running the DECwindows X server, xrn, a local emacs, a remote emacs, one local xterm, two remote xterms, a remote Synchronize, and twm. The load averages were 0.67, 0.38, 0.00. I got 14 dps. > Hmmm, seems to be some amount of variability here. Any guesses? I suppose the 3.1d vs. 4.0 could be a factor for the 2100. >Disk speed? Seems unlikely, since little I/O is being done. >Amount of memory? Possibly. What have you got? >(or just "Light" isn't all that light!). What kind of load averages were you running at? What kind of application profile? This is a perfect example of value of tiny/trivial benchmarks... -- Dave Sill (de5@ornl.gov) It will be a great day when our schools have Martin Marietta Energy Systems all the money they need and the Air Force Workstation Support has to hold a bake sale to buy a new bomber.
