Yes I know, but the amount of pagecache which is RESIDENT for a process is not that seperate from RSS, I think. I always thought RSS is the amount of mapped and anonymous pages of a process, which are in physical memory (aka resident). So I consider the amount of mapped pagecache pages of a process which are in physical memory (aka resident) a subset. Or do you care about page cache pages not mapped into the process? Is this the point I miss? Please enlighten me :-) Regards Ingo Oeser
