Virtual memory for all drives?


J

Jaime Stuardo

Hi !!

What's the reason I can have a virtual memory for each individual drive?
When I go to Performance options, under Virtual memory area, I can change
the virtual memory to be present on all drives. That's contrary of old
Windows versions, that had only 1 swap file, and I could choose in what
drive that swap file would be.

In this case, what configuration gets the best results? Is it good if I
choose the radio button "System managed size" for all drives? or I have to
do it only for C: drive and for the other choose "No paging file?

I have Windows XP professional.

Thanks
Jaime

To enhance performance, move the paging file to a
different partition. When the paging file is on the boot
partition, Windows must perform disk reading and writing
requests on both the system folder and the paging file.
When the paging file is moved to a different partition,
there is less competition between reading and writing
requests.

The optimal solution is to create one paging file that
is, by default, stored on the boot partition, and then
create one paging file on another, less frequently
accessed partition. Additionally, it is optimal to create
the second paging file so that it exists on its own
partition, with no data or operating-system-specific
files. By design, Windows uses the paging file on the
less frequently accessed partition over the paging file
on the more heavily accessed boot partition. An internal
algorithm is used to determine which paging file to use
for virtual memory management.
