That's a good thing. Inactive pages are those which back objects that used to be referenced by some program but have since been "freed" up. Instead of being marked "free", they're marked "inactive". This is part of the VM system's caching technique. If some process now requires a new reference to those pages, they may not need to be filled from disk. > I think that's why we have a slow system, specially with regard > to Pine that takes for ever to close/open a large mailbox, because it > spends a lot of time allocating memory (during that time the systems > becomes very slow)... No, this isn't why you have a slow system. Pine just sucks at handling large mailboxes. :-) Later, Sheldon.
