hi all
can anyone say if this statement is true, i have 1 gig of ram and was
curious??
If you’re blessed with a large amount of RAM (at least 512Mb), this tweak
should make Windows XP run faster than ever - it stops the core Windows
system being paged to disk, and instead stores it in your system’s RAM,
making for blistering Windows access.
Shutting off the Windows XP virtual memory paging file will hurt
rather than help the overall performance of the computer.
The main reason for this has to do with the unused portions of memory
allocation requests. All items - Windows components, device drivers,
and application programs - ask for memory allocations that are large
than what they actually need under normal circumstances. And by
design Windows must identify memory address space to satisfy all of
the memory allocation requests that are issued.
What Windows does is to allocate RAM only to those portions of the
requests that are actually used and to map the unused portions to
locations in the paging file. Note that this mapping of unused memory
requests to the paging file does not require any actual disk activity.
All that is required is to make entries in the memory mapping tables
maintained by the CPU.
In the absence of the paging file then Windows has no choice but use
RAM for all of the requested memory, including the unused portions. On
a system that is heavily used this could amount to several hundred
megabytes. For example, on my own system at this moment Task Manager
is reporting 410 mb of PF Usage. However another utility that I have
says that there is only 154 mb of active memory content currently in
the page file. So there is 410 - 154 = 256 mb of "phantom" page file
usage, which is the unused portions of memory allocation requests.
Hope this explains the situation.
Good luck
