virtual memory

[Guest]

I am try to totally understand how virtual memory works. Normally you set the
virtual memory 1.5 - 3 times you physical memory. So lets say i have 256 mb
and i set the min virtual memory to 384. what does that mean does, that mean
that when the computers 256 memory gets used up the virtual memory will take
over and use the allocated virtual memory of 384 mb? So when the virtual
memory kicks in it will start at 0 mb and go up to the max set?But here is a
nother question lets say i have 256 of physical memory and i set the virtual
min to 200 yes 200, does that mean when it uses the 256 it will use the
allocated virtual memory or does that mean once the physical memory gets used
up to 199 mb and once the computer need more than 199 mb it will use the
virtual memory since it is set a minimum of 200?

Hi,

For best performance, set the initial size to not less than the recommended
size under Total paging file size for all drives. The recommended size is
equivalent to 1.5 times the amount of RAM on your system.

Usually, you should leave the paging file at its recommended size, although
you might increase its size if you routinely use programs that require a lot
of memory.

To delete a paging file, set both initial size and maximum size to zero if u
are sure that no VM is required.

Since the subject of VMM is extremely vast and complex try from basic to
advance topics like what is page table.
