I'm hoping this is the correct list. It sounds like a Kernel issue. Feel free to enlighten me if it's not. I'm looking for a way to reload pages that have been paged out by another process. They scenario is pretty simple: I've written an application that uses a lot (100s of MB) of RAM. Users run the application (it's a backup utility). Applications does its thing and terminates. Users now complain that their system is "sluggish and unresponsive." The problem, obviously, is that as the application ran it forced just about everything else in RAM to be paged out to the VM backing files. The OS then spends the next 30 seconds, or more, paging it back in -- a period of time my users describe as "eternity." Is there anyway for my application to send a "hint" or command to the VM manager that will cause it to reload the recently paged out memory pages? I have a supervisory process (a scheduler daemon) that can do this after the process terminates. This email sent to site_archiver@lists.apple.com
