Microsoft claims Longhorn will be, er, faster

The only reason why its faster is they added a superfetch feature to the prefetcher. If you look at the key:

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.

Wow, Microsoft just added a feature that was already there in xp.


Make sure after you make the new DWORD to set it too 1.

USE AT YOUR OWN RISK

Don't forget to reboot for the tweak to be applied.

I've just done the above and after the first load there does appear to be speed increase.

If your unsure how to edit the registry copy the following into notepad call it update.reg then right click on the file you have just saved and click merge.

==========================

REGEDIT4

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters]
"EnableSuperfetch"=dword:00000001

Ok. I applied the key using Regedit, and it works (at least, my computer hasn't crashed), but I have some questions anyway.

Is it a Hexidecimal or decimal entry? I have it as a decimal.

My EnablePrefetcher was set to 5. Should I change it to 3?

Do you happen to know how this works? I'm just curious about these things cuz I don't know much about how the registry works.

What is longhorn? A link to another post or website is an acceptable answer (and time saving, too :thumbsup:).

Thanks
Lanscader

It's no longer Longhorn! It's now called Windows Vista! Check it out!

Note the people in the picture... they're not looking at the view, they're looking for Tesh Support!

Beta is out Aug 3rd! I'll be getting my hands dirty messing with it!

We're going to make the merry-go-round go faster, so everyone needs to hang on tighter-just to keep from being thrown to the wolves.

I just did it, and I notice a speed increase.

Also I left the old entry in there "EnablePrefetcher = 3" which mine is 5 though.

I just added the new thing. Couldn't create a .reg (could be cause of MSAS).


Couple of things I notice are faster: The delaying of the "All Programs" menu is pratically gone.

Firefox loads faster.

they have something addon in vista that makes the superfetch works and not in xp..
