Inquirer "Superfetch" story is crap
Posted by Steven Bink July 22, 2005 3:10 PM with 2 comment(s)
Filed under:
Iquirer posted a story called: 'Longhorn's most useful feature "leaked "as XP tweak' stating that the Windows Vista (longhorn) new superfetch feature is also available in Windows XP.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\Prefetcher

you will notice in windows xp

EnablePrefetcher = 3 and you will notice in windows longhorn
EnableSuperfetch = 1

Well, guess what? You can put the EnableSuperfetch = 1 in windows xp and get the same speed.

So I checked with Windows internals guru Mark Russinovich, he said this won't work, "SuperFetch" string isn't even in the kernel (check with strings.exe)

I never believe anything on Inquirer anyways.
Unless it is backed up from a credible source like Bink.nu

Look at Memory Management Enhancements
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/appendix/hh/appendix/enhancements5_0eecebea-e58b-4c95-8520-9b1dc2bc6196.xml.asp

for more info on EnablePrefetcher

This EnableSuperfetch is then not neccessary because EnablePrefetcher is a binary like key.

And a EnablePrefetcher=1 will have a performance downgrade...i think
