Hi I have 3 questions about Virtual memory.. in this artical they are
talking about window98!!
Any heelp would be very much appreciate it..
1)
In this artical the author saying the ration between RAM and Virtual
memory about 2:1???!!
What does that mean?? if I have a RAM of size 2M for example.. the the
virual memory should be 1M or 4M??

The amount of hard drive space you allocate for virtual memory is
important. If you allocate too little, you will get "Out of Memory"
errors. If you find that you need to keep increasing the size of the
virtual memory, you probably are also finding that your system is
sluggish and accesses the hard drive constantly. In that case, you
should consider buying more RAM to keep the ratio between RAM and
virtual memory about 2:1. Some applications enjoy having lots of
virtual memory space but do not access it very much. In that case,
large paging files work well

2) Also here the author saying if you want to improve the performance
then the
minimum and maximum size of the VM file identical??
What does that mean? and why.. I could not understand what he is
trying to say

One trick that can improve the performance of virtual memory
(especially when large amounts of virtual memory are needed) is to
make the minimum and maximum sizes of the virtual memory file
identical. This forces the operating system to allocate the entire
paging file when you start the machine. That keeps the paging file
from having to grow while programs are running, which improves
performance. Many video applications recommend this technique to avoid
pauses while reading or writing video information between hard disk
and tape

3) How can I control the VM in windowXP.
Thanks alot
