Superfetch Boosts Performance

Superfetch is an update of the XP Prefetcher, designed to more intelligently load applications into RAM based on frequency of use. With Superfetch on, your PC should theoretically get faster over time, particularly when loading frequently used apps. You won’t see improvement in general performance, like rendering Photoshop files, but Superfetch does tend to make apps load 10 to 20 percent more quickly, depending on their size.

Superfetch is on by default. To ensure that it’s active, go to the Control Panel, open Administrative Tools, and select Services. Scroll down to Superfetch and ensure that it is set to “Started” and “Automatic.”
