How do I find how much memory (real and/or virtual) is being used by a set of processes, taking shared pages into account? I see per-process numbers I can use (vmspace_resident_count and vmspace_swap_count), and overall usage numbers exist, but I can't find a better way of measuring multiple processes than adding their individual totals together. This can lead to wild inaccuracies if a few processes share a lot of pages (Java comes to mind, as do database servers). Is there some kind of reference count I can access per page, or some not-too-expensive way to see what processes are using a page? I see some things in the VM code that look like recerence counts (such as act_count in struct vm_page), but they don't seem to really be such, or at least they don't count what I'm expecting them to.
This is on 4.7. I haven't really looked at 5, so I don't know how different it is. - James Gritton [EMAIL PROTECTED] To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
