While RT tasks often need to be locked into physical memory to meet response time limits, having VM on the system may mean that useful things can still be going on in the rest of the system while some specific tasks are locked down. It may also mean that some tasks use much less memory than would be necessary if they had to be completely resident before execution. RT users typically have some performance requirements that are real requirements, but having met those they usually want to get as much more out of their systems as they can. VM helps a lot there. -- scott preece gould/csd - urbana uucp: ihnp4!uiucdcs!ccvaxa!preece arpa: preece@Gould.com
