Are you saying that pages of code segment (of an executable) which have not been accessed yet, are copied onto the swap space from their location on the disk when the program is exec'ed? Or do they remain on disk (in their original location) and loaded into memory only when accessed (and _then_ possibly swapped out)? If they remain on disk, then that wouldn't show up in swap space, right? -mandeep > > The end result is that that swap'ed pages represent pages available to be > swapped in, but not the number of pages that were actually swapped out at > some point in time. > > Greg > -- > Sent from my Android phone with K-9 Mail.
