I added it into mine. Wasnt positive if you replaced the original setting or just added the new one.
maybe its just late and I'm tired but loading programs seems snappy. Stuff like Nero which seemed to be slow at times pop right up. Not exactly a subjective testbed. I hate people saying "it feels so much faster..."

Hmm.... I think it's time to do a fresh image of my OS partition...just in case things go awry. Guinea pig?
I added it along with the existing EnablePrefetcher - 3. If you don't hear from me for a while you'll know I'm busy doing a Repair Install...
I wonder what happens if you set the value to "3"?
From the MS link:
Those include the ability to launch apps 15% faster than Windows XP, boot PCs 50% faster, patch systems with 50% fewer reboots, and let firms migrate to Longhorn 75% per cent faster.
15% ain't bad, but it may not be too obvious in a lot of cases, either.
To really give it a test I emptied my prefetch folder (except for Layout.ini). Then I opened and closed about a dozen programs several times each. (Remember, prefetching is only helpful the second time around.)
I believe I do see a real improvement. Photoshop 7, Nero 6.6, and a host of other programs all seemed snappier. I would like to see if I feel the same about it when I try it again in the morning.
One other thing to remember: You must have the Task Scheduler service enabled for prefetching to work at all. If you're not noticing any difference, see if you have it set on Automatic.

Test Number 2 - change EnableSuperfetch = 1 to EnableSuperfetch = 3.
Sooo. Did you guys just add it in alongside, or what? Did you delete the old one and replace this?...
I just added a new one and left the old one alone.
Tomorrow I'm going to experiment with different values and combinations. At 2:45am it's a little late to start cussing at the top of my lungs if something goes awry...

Discretion is the better part of valor. Yes, it's my bedtime too. I'll '= 3' a shot tomorrow.
No visible difference on my laptop at all, except maybe outlook. It appeared to open a few seconds faster but that could be my mind because I want this to work or the fact that I also disabled about 6 sevices that need not be running.

Sorry folks, it's bogus. I had such high hopes, too.
how do you dump your prefetch folder? Where is it?
NM I found it, I also deleted everything in it except the layout thing. Gonna dos ome tests now after a couple restarts and stuff.
OK I dont get it. Why are people adding new keys? Change the current key to a value of 1. Of course a new OS will not recognize new keys. They are comparing what Longhorn's Key to XP's key. They have different names but still might do the same. Anyone changed the current XP key to 1 yet and not added the Longhorn key?

EnablePrefetcher = 3 and you will notice in windows longhorn
EnableSuperfetch = 1
There evidently is no Superfetch key for XP but there is a Prefetcher key in XP. I was asking if anyone changed the prefetcher key to 1 from 3. Adding new keys doesnt mean an OS will recognize them at all so use the current one.
As far as whether adding a new key will make any difference, I'd have to look up the details but there are several bugfixes where a key is added that would never be there otherwise.
I tried something I read on the braodband site that was posted a few posts back. I put my prefetch to 12. Something wierd happened, trillian loaded almost instantly after I rebooted a couple times.
Before I did that though I made the super fetch key with a value of 1. I noticed nothing I could say was real or not. Other than when loading windows it was no faster or slower than normal when getting to the login screen. After that though when I logged in each time it seemed that the background programs I have opened faster than normal such as ATI Tools and my Wireless NIC software was able to open and connect faster each time. That was noticable and I am positive is not just my imagination as it's always been annoying the hell outta me.
Nothing great happened, and I am surely not getting higher benchmarks in 3D Mark 05. But nothing lower either thankfully.

2cpu.com has a poster that uses JEH as his handle. He has co-authored books about XP and has written device drivers etc.. for XP. Beyond what he knows he has inside sources with MS that are core team members involved with XP development and support.
For accessible XP kernel resources on the web that I know of... He is one of the very best. Easily top three in the world as far as who you can actually contact.
He says the kernel does not see this key. I believe him. I started this thread before asking him and wished I had waited. JEH is one of the top two or three XP resources available in the world on forums or email.
It is sorta funny how so many saw a serious improvement based on "seat of the pants" benchmarks. I also "thought" I saw something. So yes I too am guilty as charged.
Sort of like how I maintain that IDE raid-0 real life results are not worth the risk except for specialized situations. But many swear "it feels so much faster!"

Well, no matter how smart or educated any of us may be, we are all subject to the 'placebo affect'. Tex, I still maintain that Windows Explorer and other XP things open faster now. No, I still have no empirical data to back that up. Maybe it's just in my head, but it's faster darnit!

Yes, I realize it's for hamsters. But apparently guinea pigs have no form of excercise. You ever seen a skinny guinea? Didn't think so.
