SuperFetch is a technology that pre-loads commonly used applications into the memory to reduce their load times.
This feature was suppose to be Longhorn exclusive and it makes the OS load the applications 15% faster, boot 50% faster and install patches with 50% less reboots than it used to.

The only reason why its faster is they added a SuperFetch feature to the Prefetcher. If you look at the key in RegEdit:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SessionManager\Memory Management\Prefetcher
In Windows XP you will notice:

EnablePrefetcher = 3
and in Windows Longhorn you will notice:

EnableSuperfetch = 1

You can put the "Enable Superfetch = 1" in Windows XP and get the same speed as Longhorn!

Requires Windows XP SP2 and above.

I don't think it's real. look here:
http://blogs.msdn.co...erformance.aspx

Another potential future topic pertains to configuration changes a user can make on their own system. Many recommended changes aren’t helpful at all. For instance, we’ve found the vast majority of “registry tweak” recommendations to be bogus. Here’s one of my favorites. If you perform a Live search for “Enable Superfetch on XP”, you’ll get a large set of results. I can assure you, on Windows XP there is no Superfetch functionality and no value in setting the registry key noted on these sites. As with that myth, there are many recommendations pertaining to CPU scheduling, memory management and other configuration changes that aren’t helpful to system performance.

If I may, at the moment there are just two (opposite) theories.

Wouldn't actually testing it and report be more productive? :huh:

You do realize you are commenting on a 6 year old thread about an OS that is no longer supported? :D
