That is a good recommendation for performance.  Here is the details from this list of very good suggestions from:  http://forum.notebookreview.com/showthread.php?t=166532

 

 

 

Reduce or Eliminate the Size of Your Disk Cache

By default, Vista utilizes several gigabytes of hard disk space with a file called pagefile.sys in your root drive. Through some time and patience, Vista users with 2 or more gigabytes of ram will be able to gain a great deal of that much needed space back and increase performance by slowly reducing the 'pagefile' or disk cache, or even eliminating it.. For example, I have elected to shut down my pagefile completely whereas, previously, I had reduced it to 600mb minimum and 1200mb maximum. I decided on this after watching my RAM usage carefully and seeing that, with my use, I never came close to using 4Gb. My space savings was well over 3.5Gb of hard disk space.

On shutting it off, I immediately saw a boost in performance which was unexpected. Having done a little background as to the reasoning for this, I learned that pagefile is utilized by your system even when it is not needed. By shutting it off, you are forcing the sytem to use your RAM to its full potential.

Should you elect to reduce, a common belief is that the pagefile should be 1.5 times the total amount of your ram and the minimum and maximum should both be the same if your sure no more will be required. This will prevent excessive disk activity at times when it is required for the pagefile to expand.

USER ALERT!!!! Reducing your pagefile size by too much will severely slow and cripple your system as it cannot create a large enough disk cache for the job at hand, thus resulting in a great deal more disk activity and slower system.

Now...how to get there....

1. Go to:Control Panel/System/Advanced System Settings/Performance Settings/Advanced/Change;
2. Make note and write down the present system managed pagefile size;
3. Disable the 'automatic' or 'system managed' size;
4. Slowly and carefully reduce your pagefile over a period of time by creating a custom size; and
5. If you find your RAM use remains on the low end of the pole after some careful monitoring, just turn it off completely and enjoy.

Good luck and enjoy the newly regained disk space!!

Whilst I'm sure there will be a number of forum members who'll find that advice useful Jake... it would've been even more useful, if you'd also advised/added how to disable the paging file ;)

I find it somewhat odd that you have this problem and have to resort to disabiling virtual memory.  I have a similar system and have not seen this problem.  In fact what I have found is that there are some game sthat work better if one maintains their disk cache around 3GB.  BTW - I also use a 2GB fast SD card for ready boost and am using the lastest driver downloaded from NVIDIA which I think is 175.35.
