How to Disable or Enable Superfetch in Vista
Superfetch is a new improved feature in Vista that monitors which applications you use the most and preloads these into your system memory (RAM) so they'll be ready when you need them. It treats system memory like a cache much more aggressively and effectively than any other version of Windows. Superfetch will help Vista prioritize background programs, (EX: Disk Defrag and Windows Defender), at a low priority so that they can do their job while your work always comes first. The folder Superfetch uses is located at: C:\Windows\Prefetch
Sometimes Superfetch may cause a bit of a longer startup as it loads everything into memory and your hard drive is running more to preload this data for Superfetch into system memory. This should improve over time as Superfetch learns by building a profile of your usage habbits and applies this information to it's prefetching decisions.
This will vary from person to person and with how and what type of system you have set up. Try turning OFF Superfetch and see for yourself if your computer runs faster with or without it. You can always turn it back ON. In most cases your computer will run faster with Superfetch on after the initial loading into memory at startup. Superfetch may not be helpful for a server since it is always being ramdomly accessed.
