Prevent Paging Use

Archived from groups: microsoft.public.windowsxp.general (More info?)

Hi,

After a few hours of research, I am unable to find a decent solution for the
following situation I have:

I have 768 MB of 400Mhz RAM, but a reasonably slow HDD, I would like to make
sure Windows uses the majority of this RAM before it decides to go
destroying my hard disk using the paging file.

I however do not want to be left without virtual memory in extreeme cases,
as I have a 1GB paging file at the moment 'just in case'. Would there be any
settings that would ensure windows uses the physical RAM foremost, paging
file second as I appear to have 3 or 4 hundred MB of physical RAM left and
400MB of paging used.

Any ideas or configs would be appreciated.

You don't need to do anything. You can't turn off paging. You can only make it slower.

It's not so don't worry about it. That 406Mb is being used - windows will just stop using it if needed.
Each process opened will add to the page file used. Turn off your pagefile and watch page file used increase. Systeminfo will tell you the amount of your paging file used. Task Man doesn't - it tells you reserved memory in the PF and EXE and DLL.

If you add your system cache and available memory it normally exceeds physical memory. That should give you the hint. Most of your available memory is system cache. And as you have a slow hard drive that is important to you. Windows constantly takes memory away from programs to see if a PF is generated. If it is it gives it back. If it isn't then it gives it to somethinfg that does need it.

Even the MS programmers don't understand the fine detail of memory management (except for the memory management team).

There are hard page faults and soft page faults. A hard fault means
the page needs to be read from disk, a soft fault takes a few
microseconds but does no I/O. d

Page faults are normal. The "hundreds of thousands" of page faults you
see may be normal for system startup. Start counting after the system
is up and stable.

Page faults generally happen when you switch between applications.

Look at the perfmon tool instead of taskman. It can give you lots more
detail. I suggest you monitor counters for pagefile reads/writes.
