Microsoft claims that Longhorn will be faster because they added a Superfetch feature to the prefetcher.
In Windows XP, if you look at the key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters you'll see:
EnablePrefetcher = 3
In Windows Longhorn you should see:
EnableSuperfetch = 1
So what do you know? You can put the EnableSuperfetch = 1 in Windows XP and get the same speed.
Microsoft just 'added' a feature that was - already there - in XP!
Just a note on the key name:
Add DWORD
EnableSuperfetch = 1
Which will look like this.
(EnableSuperfetch REG_DWORD 0x00000001 (1)
Anyone tried it yet and found an improvement?
Are you supposed to leave the EnablePrefetch key in place?
