| Page File Transfers Chart |
The Page File Transfers chart shows recent Windows paging activity. It shows the number of pages read (in) and written (out) per second to and from the Page Files. Paging occurs when the Windows Virtual Memory Manager moves data or code between physical memory and disk. Sustained high paging rates can degrade system performance significantly. | ||||||||||||
| Page Faults Chart |
The Page Faults chart shows the rate at which Windows is processing page faults. It compares the two types of page fault (soft and hard) and makes it easy to see the ratio between them. A page fault occurs when a process references a page that is not in that processes working set (the set of pages visible to that process in physical memory). When this happens, the process has to wait while the Windows Virtual Memory Manager retrieves the page from virtual memory.

Code and data is moved between physical memory and the page files as required, giving processes on the system the illusion that there is much more physical memory available than there really is. The process of moving data and code between memory and disk is called paging. The Page Files grid shows the following:
