you can use the Task Manager to monitor Page File usage. Just Ctrl- Alt-
Del and select Performance. the other thing you might want to do is select
Options and uncheck "Always On Top" It will still be displayed but items
can cover it if you want to.
That PF Usage value is worse that useless for assessing the potential
benefit of adding more RAM.
For example on my computer at this moment Task Manager tells me that
PF Usage is 525 mb. However my actual pagefile (C:\pagefile.sys) is
only 88 mb in size. It is pretty tough to actually use 525 mb of
space in an 88 mb file.
The reason for this is because Task Manager includes "phantom" page
fiel usage in the reported value, especially the unused portions of
memory allocation requests. By design, Windows must provide memory
address space to satisfy all of the memory requests that are issued by
Windows components, application programs and device drivers. And
also by design pretty much every one of these items asks for memory
allocations that are larger than what they usually need under normal
circumstances, sometimes very much more. So what Windows does is to
allocate RAM addresses only to those portions of the requests that are
actually used and to map the unused portions to available locations in
the paging/swap file.
With Windows XP the swap file space does not even have to exist, it
just has to be able to created if and when needed without exceeding
the maximum size limit for the pagefile. On my computer the pagefile
hast the maximum set at 1 gb. Also note that this mapping of unused
memory requests to the pagefile does not require any actual disk
activity. All that is required is to make entries in the memory
mapping tables maintained by the system.
Hope this clarifies the situation.
