hd use in vista64

mike2h · Jun 7, 2008, 06:34 AM

my hds take forever to finish working once i get into vista - takes about 25% longet to login & easily 3x as long for hds to stop working once im at desktop. seems like they tend to work a lot more all around to.
hd config is exactly the same as it was for my xp pro setup & they r definetly definetly defragged

any ideas/clues?

One word for you, Superfetch. Conventional Windows Caching - Tom's Hardware : Windows Vista's SuperFetch and ReadyBoost Analyzed

Basically what happens is Vista tries to keep a pattern of programs that you use and tries to load it into memory automatically (even without you running it). It can even track of days / programs you run. So if you run IE every Monday morning Vista would automatically run it every Monday morning when you start it up.

It works at a lower priority than "real" tasks. It temporarily stops preloading data if run a program and load the data of the program you ran first. Afterwards it will continue preloading the data it was trying to load.

Some people swear by it and say it's the best feature of Vista. But to me, it's just disk thrasing. You can turn it off if you want by typing services.msc into your run command and right click on Superfetch to stop the service and disable it.

i find that it takes about a week for the system performance to smooth out with the thrashing.. and about another month before everything is fine an dandy.

It's like having an AI predict what your planning on doing, and quite often it doesn't get it wrong when you give it enough time to learn your habits...

After it gets sorted, there is a considerable improvement over having it disabled...

HD use on bootup isn't going to settle down, most of it is precaching data, so the more ram you have, the longer it takes. However, it runs at low priority, so doesn't impact computer usage while it's precaching

Unless you reboot multiple times per day, and want to reduce HD use for some reason other than performance, I wouldn't worry about it.

This is a feature I've actually grown to love
All my most-used apps load instantly once my computer is booted and ready

I'd leave it on unless you are running a very old/almost dead hard drive

Most of "us" will keep upgrading our main hard drives anyways (Velo-300 anyone?)
