What trump would that be?
You've gone off on a tangent again. I repeat my questions!
Your statement "is too large and windows simply won't use all that
additional space. In fact, it actually degrades the performance of
the operating system and wasting valuable disk space as well." set me
wondering how you might justify what you have said!
Free disk space is valuable if you have insuffient and less or not
valuable if you have plenty! Explain how free disk space has to be
valuable?
Why would an overlarge pagefile degrade performance?

Hope this helps.

actually, although it seems you
are providing a courtesy, it was simply
an attempt to create controversy.
as far as I am concerned you can set the
vm to any size that you think is best for your system.
you seem somewhat reasonable therefore you would also have
reasoned that if I wanted your opinion i would have
asked for it.
I stand by my suggestion because it will help the
o.p., whether or not you like it. If you have strong
reservations about setting the vm at a fixed size, then
please forward them to the microsoft software engineers
so that they can remove the feature / option.
until then, i will continue to take advantage of
the option windows has provided and provide
it to computer users who are encountering
difficulties with their vm, similar to what
is described by "MICROSOFT":

Sorry DB you've gone off on a tangent and ignored the questions I
posted.
Thanks, however, for adjusting your line length.

The aspect of virtual memory you refer to as a machine limitation is
not! It is a default setting, which can be changed by the user.
When you refer to most users would not use 50 mb I think you will
find it more than likely that most do but not all of the time.
However, I am not aware of any published statistics. Usage is not a
constant. All users use some pagefile memory, whether they run out of
RAM
memory or not. Adding RAM can reduce but not eliminate pagefile
usage. Your comments about the suitability of 512 mb are a
generalisation.
The amount of RAM required for satisfactory performance depends on
intended use.
Before you reply to the questions I asked have a look at this

hmm? my previous posting was a draft
not sure why it got posted. however, i hope
this posting is better understood.....
--------------------------
the vm is a machine limitation.
in this case, the limitation is based on the physical memory size of
your
the ram chips. let's say you have a pc with 64 megabytes, of course
this is only an example.
the virtual memory was designed to help move data in and out of the
physical ram onto the disk in a special file called pagefile.sys
mathematically a 1 to 1 ratio could be used. so if you only have a
64 megabyte ram chip, then all it can mechanically move to and from
the pagefile.sys is 64 megabytes of data.
if one tries to set the size of a pagefile to a size 1000 megabytes,
the machine will still only use 64 megabytes because of the physical
ram.
the above is only an example is an extreme only to help illustrate
and
explain.
lets say that the vm has been set to a max size of 1000 megabytes
but you only have a 64 megabyte ram chip, then approximately 936
megabytes of disk space that can be used for regular data is instead
locked up /
reserved for vm eventhough the o.s. can't use it. frankly, most
regular computer users never use 50 percent of the virtual memory
anyways. so in
this example, most users would not use 50 megabytes of v.m.
however, powerusers, and high end graphics programs run out
of ram memory and virtual memory likewise, so one of the easiest
options is to gain more power is to increase the machines ram.
it would be wonderful that all computers could have a 64 megabyte
chip and by simply maxing out the virtual memory say to 4 gigabytes
would make any computer into a super computer with lots of memory -
but we aint' there yet.
the best way to improve performance is simply have enough ram
installed. unlike
my example of 64 megabytes, windows xp simply could not function
with this
limitation. most computers are optimized for 512 megabytes of ram.
they
might sell a pc with less ram, but it is done not only to reduce the
cost of a pc,
but is sufficient to run windows, excluding all other third party
softwares.
acquiring and purchasing more ram than a regular pc user needs
will likely be a waste of money for the regular pc user. at the
same time
havng too much virtual memory will be costly to your computer and
waste valuable resources.

Your posts must have the shortest line length in these newsgroups.
Is
this necessary or could you make them longer?

actually, if the virtual memory too
low message implies that the space
reserved for it is insufficient.
for example let say you have
512 megabytes of ram. logically
the maximum size of the vm should
be 1.5. So the max should be set
at 768 megabytes.
however, if the max is set like 100
megabytes instead of 768 megabytes
your machine will tell you that the
vm is too low.
now let's say you want to set the
max range beyond 768 like 2500
megabytes. your machine will not
cry out about vm being too low,
however, 2500 megs is too large
and windows simply won't use all
that additional space. In fact, it
actually degrades the performance
of the operating system and wasting
valuable disk space as well.
in regards to the minimum size this
is simply a low side of the range.
as mentioned, go ahead and take
the time to optimize your system.
by trying different ranges or settings.
however, i always suggest as a
default fix for low vm is to set
it to custom size of min=2 and
max=1152.
1152 may be too much for
some systems, but it works fairly
well and can be adjusted to be
lower or just left as is.
after you find the optimum
size for your vm. let me know
and I can provide additional
fyi to help you monitor your
new settings....
but first work on the initial
issue your o.s. is having....

the initial size is the minimum windows
permits. if you look at the configuration
dialog for the virtual memory, it indicates
the minimum allowed. but you can also
input a 0 or a 1 and you will get a simple
message about it.
you don't have to use 2 and can test your system with
higher sizes, that is if you have the time and
patience. something to realize however, is that windows
will not use more virtual memory than
is necessary. if i'm not mistake the limit is 1.5 times
the size of your physical ram.
so if you max out your page file with
a high amount say like 5 times the ram size, you
will only be wasting that additional space that
has been reserved for vm but "will not" be used by windows.
although automatic resizing is a convenience
for users, it is not always the best option for
some systems, especially the older ones. Thus
windows nags about the low virtual.
my systems are optimized with custom sizes
and i never get that nag. however, other systems may
use the automatic resizing just fine and never get the
nag as well.

you can try an custom/initial size of 2 and
max of 1.5 times the physical size
of your ram.
Can you explain an initial size of 2?
