Gordon, I'm not sure I follow you. We use shared memory for most of the heavily-used utility routines and big entry programs that get run simultaneously by multiple users. I'm pretty comfortable that I've chosen programs wisely. As I understand it, each of those programs will be loaded into memory when they are called for the first time.
Besides that, there are hundreds of programs that are not shared, and occasionally run. I would think they would routinely get swapped out of cache since used so seldom. I suppose there might be many in that grey area, the ones that didn't quite make my cutoff for sharing, but really do get called a lot. You're thinking those would have a significant impact? cds -----Original Message----- From: Gordon Glorfield Sent: Wednesday, November 10, 2004 12:25 PM I think you are probably close. It's probably caching but not data. I'd say it was probably the programs themselves being cached. > -----Original Message----- > From: Stevenson, Charles > For the first day after a reboot, our Universe application seems to be > extraordinarily slow; [snip] > Has anyone else seen this sort of thing?
