Understand how SuperFetch uses RAM to enhance system performance – TechRepublic
Microsoft Windows Vista uses an applet called SuperFetch to manage memory. Greg Shultz explains how SuperFetch works and what it does to enhance the performance of your system. He was happy with the system’s overall performance, but he was concerned about the amount of available RAM on his system.
He told me that at any given time while using the system under normal conditions, with very few applications running, he would access the Performance tab in Windows Task Manager and discover that the amount of free memory in the Physical Memory panel would read 10MB or less. He was surprised that there would be such a huge difference between the two operating systems’ use of memory and came to the conclusion that Vista was just a memory hog.
He then asked me what would cause Vista to use all of the system’s available memory? My answer to him was that what he was witnessing was a Vista performance enhancement called SuperFetch and the fact that he had very little free memory available was a good thing — not a bad thing.
Since other Vista users may have the same reaction as my friend, I thought that a detailed explanation of how SuperFetch works would make a good topic for the Windows Vista Report.
However, if you convert both figures to gigabytes, it looks more equal. Both systems are running only Internet Explorer and Paint. But, if you look at the available memory in XP, it comes out to be about MB. Yet, the Vista system has only5 MB of available memory.
The reason for this difference is that Windows XP treats RAM as a resource to be used only when needed while Vista treats RAM as a cache and uses almost all of it as soon as it becomes available. The SuperFetch memory management scheme is multipronged. To begin with, SuperFetch tracks the applications that you use most often. As it does so, it builds a database and constantly updates it as you work. Using this database as a reference, SuperFetch instructs Disk Defragmenter to make sure that those applications are strategically positioned on the hard disk where they can be loaded into memory very quickly with the least amount of physical movement of the hard disk’s read-write heads.
Then, each time you turn on your system, SuperFetch preloads those applications that you use most often into memory. As such, when you actually go to run your favorite application, it loads up much more quickly from the RAM cache than if it had to be read from the hard disk and loaded into RAM. While the process as I’ve described so far sounds like a complete system, it’s only part of the picture — SuperFetch has a much bigger role to play in order to keep this system as effective as possible over time.
As it does so, SuperFetch keeps track of the previous priority levels in order to ensure the system remains responsive over time. For example, let’s suppose that you’re writing a document in Word and have been working on it steadily for a while.
When you go to lunch, Word becomes inactive and other background tasks, such as Disk Defragmenter, realize that the system is idle and begin to go to work. Now that you know that Vista treats RAM as a cache rather than as a resource, you can understand why the amount of free memory in the Physical Memory panel on the Performance tab in Windows Task Manager is very small figure.
