Now, when you return to your desk, your programs will continue to run as efficiently as they did before you left.

Windows SuperFetch prioritizes the programs you're currently using over background tasks and adapts to the way you work by tracking the programs you use most often and pre-loading these into memory. SuperFetch keeps track of which applications you use most and loads this information in RAM so that programs load faster than they would if the hard disk had to be accessed every time. This new functionality is called SuperFetch. In Vista, the Prefetcher has been tweaked and changed to be much more aggressive and intelligent in its caching to give even greater performance. The Prefetcher is in charge of storing program information so that often-used programs and processes can run faster. We will also be discussing Vista RAM usage since these all work together.įirst, SuperFetch is an enhancement of the Prefetcher that you have probably seen mentioned in previous versions of Windows. Today we are going to discuss two new Vista performance enhancements, SuperFetch & ReadyBoost.
