Description
The system cache seems to be working in a weird way and I am not sure if this is intentional. On my system it seems that the amount of memory in use plus cache equals around 50% of my total memory (2 Gb total). When the memory usage goes up, the cache memory use goes down in a proportional way even with plenty of free memory available (see attached screenshot. Ignore the initial 0 values close ton the current position. It seems to be a bug in ActivityMonitor reported in a different ticket). Is this intentional? It does not really make sense because when the memory usage goes close to 1 Gb, the cache drops down to close to 0 and, as I mentioned, there is 2 Gb of memory on this machine.

Well, that's pretty much what I wrote in the initial commit message of ActivityMonitor: the way the cached_pages stat is computed is just not correct.

I guess I missed that message. Well, at least the bug is documented now.

This seems to be a moot point now with recent fixes from Ingo. Closing this bug.
