OK, did a bit of research and have your reason why. All those sites telling
you to do this don't have a clue. Using that setting actually hinders
performance on Win98. Read the below.

http://www.racesimcentral.net/;EN-US;q223294

Windows 98 added a new feature, PageFile_Call_Async_Manager, that allows the
Memory Manager to asynchronously write out page file (swap file) buffers
during periods of time when VFAT file system activity is not busy.

This feature can affect the behavior of VxDs that monitor and/or otherwise
intercept PageFile VxD functions. This article is applicable to you if your
VxD hooks PageFile_Read_Or_Write, and you discover that you are not seeing
all the page file traffic when using Windows 98.

MORE INFORMATION
You can disable this feature, causing the system to behave as Windows 95
does, at some cost in overall system performance. Add the following entry to
the System.ini file, in its [386Enh] section:

[386Enh]
ConservativeSwapfileUsage=1

I'm not, but maybe Tim is.

There you go.  Seek and ye shall find...but troll and someone will find it
for you.  Thanks much; I have remmed out CSFU=1.

I read the webpage but could not quite decipher the
meaning
could you explain it a bit here ???

All those sites telling

What more is really needed?
You can disable this feature, causing the system to behave as Windows 95 does, at some cost in
overall system performance.

If it hurts overall system performance in 98 and higher, why would anyone use it?

  perhaps what you should have done is test the theory....run 3dmark then
rem it out, reboot and run 3dmark again...

What Biz said basically. I'm not an MSCE so it's hard for me to understand
the technical jargon too. But, my interpretation is that Win98 and up swap
data buffers in/out at the same time, Win95 can only do either in or out at
once. Therefore, making Win98 behave like Win95 with that line added to the
system.ini is detrimental to performance. Of course you won't be able to
benchmark this with  3dMark because it affects the behavoir of virtual
memory and not video card performance.

How about PCMark2002 ?

Duh!  Sorry about that, I meant Biz's post:

"Honestly, I haven't been able to witness any performance differences by
setting it manually or
leaving it to let Windows manage.....so I think its a bunch of baloney on a
well-tuned system..."

Now that I think about it, I really meant the original post in this debate .
. . yeah, that's the ticket . ;0)

Does it test the swap file? Probably not.
