I plan to use a small partition on a 2nd hard drive
for the pagefile.

Is there a recommended cluster size for it?

How does one cause the pagefile's partition
to be on the outermost cylinders of the hard
drive?


Thanks for any info.

This is getting to obsessively anal again.

The thing to do first is to ensure that the system has
enough physical ram to minimise the use of the pagefile.

Basically with a defragger that allows you to control that,
particular with fixed page files, as opposed to page files
that are allowed to shrink and grow as the need arises.

But again, it makes much more sense to have enough
physical ram so the pagefile isnt used much.

My physical RAM is maxed out. Is there a "best" or
recommended cluster size for a pagefile in a dedicated
partition?

A de-fragger can control a *partition's* location?
Which de-fragger can do that?

But again, my RAM is maxed out.

No matter what you do to it a disk is thousands of times slower than
RAM--fiddling the page file is going to have a tiny effect on
performance when compared to putting in sufficient RAM.

Put the page file on the _first_ partition on the drive and don't use
that drive (not that partition, that whole drive) for _anything_ else
and you've pretty much done what you can.

Then the only thing that makes any sense is to
replace the PC so you can have more physical
ram and a much better power supply etc as well.

No obsessive fiddling with the page file detail will produce
anything like as good a return performance wise.

And you'll get a noticeable improvement
from the increased FSB speed as well.

There can never be any such animal.

It varys with the file structure used, FAT32
or NTFS etc, and that other factor of a fixed
pagefile or a dynamic one matters as well.

And its all mindlessly anal when it makes a
hell of a lot more sense to cut to the chase
and replace the system and have enough
physical ram so the page file isnt used at all.

Nope. The location of the partition is set a partition creation time.

But unless you have a dedicated partition for the page file,
you would normally want to control where the page file is
in the partition if you're getting that anal about page files.

And even a dedicated partition for the page file has its
own downsides because if its on the same physical drive
as the partition which is seeing the most disk activity, the
heads can end up moving much further between the two
partitions when the system is excessively paging.

If you want to get obsessive about optimising page files,
you really need the page file on a different physical drive
to the one which is seeing the disk activity, and it needs
to be on a different controller too, and it cant be some
dinosaury old small drive, because its performance
may well be rather poor just because its a dinosaur too.

And when you are getting that obsessive about the page
file, it makes a hell of a lot more sense to do whatever
it takes to have enough physical ram so the page file
isnt used at all, because thats an order of magnitude
or more faster than any page file on a drive can ever be.

>> But again, it makes much more sense to have

> But again, my RAM is maxed out.

But again, the only thing that makes any sense
is to replace the motherboard so it isnt anymore.
And get a big bonus with an increased FSB
speed, and get a decent power supply instead
of the puny weakling you currently have as well.

Even a desperate pov wouldnt have to flip too
many burgers to be able to get a decent system.

I have 2 hard drives. The 2nd hard drive lives
inside the PC. It is there. It is not going away. It
has lots of room. There is lots of room on it for a
partition to devote to a pagefile. I do not want to
buy or make another computer. Is there an optimal
or advisable format for the pagefile partition given
that the rest of the system is formatted NTFS?

I said at the start that the partition is dedicated to the
pagefile.

The 2nd hard drive, where the pagefile will be, will see
virtually no other use in normal operation.

The 2nd hard drive will be on its own channel on
an Ultra ATA 133 controller card.

More RAM, as I've repeatedly explained, is not an
option.

Completely irrelevant. The only thing that makes any sense is to
replace the PC so you can have more physical ram if its using the
page file a lot now, and a much better power supply etc as well.

It should. Into the bin.

> It has lots of room.

What matters is whether that hard drive is a decent
modern high performance drive, if you're too stupid
to add more physical ram, however its necessary to
do that, if the page file is currently getting used much.

> There is lots of room on it for a

There is a hell of a lot more involved than just room, child.

More fool you.

Nope, it depends entirely on the detail of that hard
drive. Whether its on its own channel, whether its
some old dinosaur with lousy performance, etc etc etc.

And all of that is completely stupid compared with
adding more physical ram, however its necessary to
do that, if the page file is currently getting used much.

>> But unless you have a dedicated partition for the page file,

Thats not neccessarily the best approach either. If that
physical drive is being actively used at the same time as
the pagefile is being used, because you are stupid enough
to use a pagefile instead of more physical ram, you can
get better results with a fixed pagefile in the same partition
as the other drive activity. Just because the heads dont have
to move between two sets of partition directory structures etc.

And NTFS isnt necessarily the most appropriate format
for a dedicated partition for a page file anyway, because its
optimised for data security and you dont need that for a pagefile.

Even more likely that its a dinosaury old drive with lousy
performance thats useless for a high activity pagefile.

You may even find that the use of that old dinosaur for the
pagefile gives significantly worse performance than having
a fixed pagefile on the main boot drive, particularly if the
main boot drive is a decent modern high performance drive.

It may well still have significant worse performance than
a fixed pagefile on the main boot drive, just because it
may well be some old dinosaur of a drive, and the total
performance of the drive subsystem may well be rather
worse than with a fixed pagefile on the main boot drive
if that boot drive is a decent modern high performance
drive with a decent bandwidth motherboard controller etc.

Its ALWAYS an option. And the only sensible one too.

A 4K cluster size (which is the NTFS default for an aligned partition
and also the FAT32 default for partitions smaller than 8 gb) will be
an exact match for the 4K memory page size.

As some paging file activities will involve a single memory page this
is probably the optimum size. This is more relevant to Windows
95/98/Me where swap file operations are always done in 4K (single
page) blocks. Windows XP will aggregate page file reads and writes to
span multiple pages.

But as "Rod Speed" says the best situation for the page file is to
have enough RAM so as to eliminate or at least minimize the need to
actually write to it.

You can check on actual page file usage with a free utility from
http://www.dougknox.com/xp/utils/xp_pagefilemon.htm or from
http://billsway.com/notes_public/WinXP_Tweaks/

There is probably about 20 mb of stuff in RAM which can be moved to
the page file and which will rarely if ever be needed again. But if
the actual page file usage gets up to the 50 mb level or more on a
regular basis then that is pretty conclusive that there is
considerable paging in and out occurring and a RAM upgrade would
almost certainly be beneficial.

Note also that a dedicated page file partition can be
counter-productive in some instances. This is because much of the
paging file activity occurs interspersed with other disk activity such
as starting a new application program or opening a new data file. If
that is being done from a different partition on the same physical
drive as the paging file then the increased travel distance for the
drive head mechanism as it shuttles back and forth between the two
partitions can slow things down.

On the other hand, if the item being loaded is on a different physical
hard drive from the paging file then performance will be optimized
because the drive head mechanism can remain positioned at the page
file location.

Good luck

I see no messages in this thread in which you give any reason why more
RAM is not an option. In fact I can't find any post from you anywhere
that explains why.

My impression is that you're struggling to make an obsolete machine do
things that it is not capable of doing. Simple fact, if the machine
doesn't have enough RAM to do the job you need to do then you can tweak
the page file until Hell freezes over and it's still not going to have
enough RAM to do the job you need to do.
