Accelerate Windows by Tweaking Virtual Memory
Posted on Feb 25 2008 07:31 AM by xper in Guides

If you poke around tip sites, you'll find a lot of myths and harebrained theories about optimising virtual memory (the hard-disk space Windows uses to supplement your RAM) -- a few of them even perpetuated by me. This time I went to the horse's mouth for the Microsoft-approved ways to set Windows' memory management to full steam ahead.

If you have only one hard drive, just leave well enough alone. But if you have two or more internal or external hard drives (not just disk partitions), your PC will be peppier if you keep the default paging file (what Microsoft calls the virtual memory disk space) on your boot drive (the one that holds Windows) and add a paging file to the second drive.

One of the best system improvements you can do is exclude the c:\pagefile.sys from your virus scan. Because you're computer reads & writes to it so often, and the fact it's so big (1.5gb or more), makes it tax your AV scanner heavily.

And when you think about it, this does not open the door for virus infection as it's only a copy of your ram, which is already scanned in realtime, which comes from files, which are scanned before they're ran. So basically you've already scanned the data twice, there's no reason to scan it a 3rd and 4th time when you write and read to the pagefile.
Actually, most modern AVs do not scan the pagefile at all.

Also, instead of excluding the pagefile, why not just set the scanner to scan only executables? That'll save even more resources. I mean, what are the chances that someone might get infected by an mp3 or avi file?

Or better yet, run as a limited user and follow other safe computing practices and you won't even need to run an antivirus :)
