I am trying to force the Memory Manager to use any "unused Physical memory"
before the page file is used. Does turning off the page file help? How about
setting a larger "System Cache" size?
 
no turning off the pagefile does not help, unless
you have more than 2 gigs of ram.

you can system control panel, advance tab, performance,
advaned tab and memory usage and change to system cache....
 
Programs will request pages/memory that will then be assigned to the
pagefile, if there is sufficient real memory the info will not be paged
out, but turning OFF the page file will cause you some grief sooner or
later. It will not help to do that.

It generally does. Do not confuse allocated memory in the page file with
memory in use in the page file.

No, and that's a very bad thing to do.
Turning off the page file can never help you (if you don't need it, it won't
be used), and can often hurt you. Virtual memory allocations are often made
before any need for them arises, so they will be there if you need them.
Without a page file, those allocations have to be made in real memory, and
the result is that real memory gets tied up and is unavailable for use.


So the result of turning off the page file is that you won't be able to use
all the RAM you have.
 
Is sufficient real memory "unused physical memory"?

So does the Wxp Memory Manager always use unused physical memory
before using the page file?

How can I force the Memory Manager to use unused physical memory for casheing?

It generally does, as I said.

It generally does. Don't try to force it to do anything. It works very well
on its own, and attempts to interfere with what it does are
counterproductive.

Unused physical memory is unused real memory. As XP is a virtual memory
operating system, it isn't useful to think that physical memory has the same
meaning as in Win 9x.

If left alone, Windows XP will attempt to use ALL physical memory to
enhance performance, and will shift memory use internally as needed. If
you continue to load new programs and data, the system will eventually
have to page something to disk. You are not likely to improve the
assignment by arbitrarily limiting things in one way or another, and
will result in memory being "reserved" but not used. This is one of the
"schemes" that "fix-all" utilities claim to do to improve the system,
while actual testing has shown that the only thing that has been
improved is the company profits.
