Page File counter and Private Bytes Counter

[George2]

Hello everyone,


I am not sure whether I am wrong or the Windows Internals Book 4th
version is wrong.

Here is what the book says in Chapter 7, Memory Management from Page
444 to Page 445

--------------------
Thus, the Process: Page File Bytes performance counter is actually the
total process private committed memory, of which none, some or all may
be in the paging file (In fact, it's the same as the Process: Private
Bytes performance counter).
--------------------


This is what help from perfmon said about Page File Bytes Counter

--------------------
Page File Bytes is the current amount of virtual memory, in bytes,
that this process has reserved for use in the paging file(s). Paging
files are used to store pages of memory used by the process that are
not contained in other files. Paging files are shared by all
processes, and the lack of space in paging files can prevent other
processes from allocating memory. If there is no paging file, this
counter reflects the current amount of virtual memory that the process
has reserved for use in physical memory.

Private Bytes is the current size, in bytes, of memory that this
process has allocated that cannot be shared with other processes.
--------------------

Absolutely Page File Bytes and Private Bytes are different. Any
comments?


thanks in advance,
George
