the confusing term page file
On Windows Server 2003, task manager there is a term called PF (Page File) and it has a related curve. Task manager also has another term called commit charge.
1. I think PF is the same as commit charge. Previously, I think Page File only includes the paged-out pages which physical memory can not contain, and the pages are not in memory are counted as PF. Now I think I am wrong and PF includes all committed pages, including the ones in memory and the ones on disk;
2. Even if the pages are marked as COMMIT, it is not always counted as a part of PF in some situations before it is actually used (request for zero and copy-on-write scenarios);
Are my understandings of (1) and (2) correct?
thanks in advance,
