Excel will launch so fast, you’ll be confused and could think, “Did I even want to use Excel? I hadn’t even decided and here it is.”. Unfortunately, Superfetch is so pumped about doing it’s job that it is always one step ahead of the user. And the user thinks about doing a lot of stuff. Thus, the hard drive is sad and so are we. Shut it off. [...]

Superfetch services no real purpose for most users. If you want quick access to all your applications, just start them up and collapse the window. When you need them they are there and ready.
If doing that doesn’t make sense to you, then superfetch certainly doesn’t make sense either.
To a naive user running only a few small apps, superfetch will seems great because when you push the start program button, it launches much faster (1-10 seconds). It does this because the OS pushed the button for you … while you waited.
Or you could simply put your favorites programs in the start up options.
There are purposes for the superfetch type software, but you would be hard pressed to find real world applications for it.
There are some speed advantages having programs already in page file format … but it is very small. In fact systems requiring that level of performance simply lock programs in memory … swapping should never occur.
Lastly most PC hard drives (IDE/SATA)do not have the performance characteristics required to avoid system degradation from superfetch. Oddly enough, high performance disks need superfetch even less.

That still does not help.. lol Especially if Superfetch is using so much darn memory. Especially as much as it is using.
Is it safe to disale Superfetch?
lol,
Yes, it’s perfectly safe to disable superfetch. Superfetch is supposed to be a good thing though, speeding up programs you most often use the next time you start them. I’ve just chosen to go on without it, no reason in particular. Right now I’m trying to determine how many services I can safely disable.

My friend has disabled superfetch and he has no problem.So don’t listen to those idiots who are eating a lot of shit.

I see this as a double-edged sword. It’s basically a precaching mechanism, which sounds great in theory. Windows 98 contained a feature in the new memory management subsystem where the MM would *very* proactively page out things so that more memory would be free for more things to load up. What’s the correlation between the two? They both sound like fantastic ideas and may SEEM to make sense, until they’re actually implemented in a real-world situation! The 98 MM would start paging out programs as they loaded, which caused the slow boot times compared to 95 (yes, I’m ignoring the ConservativeSwapfileUsage option here, OK?) and the end result was that the memory wouldn’t be used to maximum benefit, and the scalability of the system proved HORRIBLE when people started running 98 on machines with 128MB instead of 16MB–you’d have 60 megs of your Norton crap PAGED OUT at boot time, and end up with half your RAM unused and tons of wasted paging thrashing.
The Vista SuperFetch idea is much the same way. Granted, the WinXP prefetcher did a nice job of speeding XP boot times, and it’s limited to 5MB of prefetch data so the strain it could cause is quite minimal for even a slow P2. SuperFetch, however, is death overkill as I see it. Rather than simple prefetching, it keeps the hard drive running constantly, and despite the fact that it runs in a very low priority level, the I/O adds additional strain to the system because eventually it must be serviced, despite the process or thread priority that’s asking for it. Pile SuperFetch on top of System Restore, the search indexing engine, and standard-issue Windows NT anticipatory/demand paging operations…and you’ve got a LOT of I/O going on.
Combine this with the fact that the RAM eaten by SuperFetch tactics could be allocated to system cache instead, and you’ve got some ugliness. It’s not super bad, but much like tuning a car to get better gas mileage, it’s one place where you can drop some of the weight and make the machine run a bit better. The only time I can see an advantage to SuperFetch is if you run irresponsible crap like Norton, which has this new “Sonar” feature that I’ve seen eat 1.3GB of RAM when it decides to go into a random scanning operation. Bottom line, if your app needs so much of your RAM that you need SuperFetch to make up for it blowing your system disk cache away all the time, JUST BUY MORE FRICKIN’ RAM. IT’S $40 FOR A GIGABYTE OF DDR2 MEMORY, PEOPLE! $40! That’s 1024MB more memory to hold that fat application! YOU DON’T NEED THIS CRAP. Turn it ALL OFF!!!

Superfetch was meant for systems that are constantly left on, or reliablly can move into and out of sleep mode. On systems that crash a lot, or need to be rebooted a lot, or can not reliably come in and out of sleep, Superfetch is one royal pain in the ass, as it thrashes your harddrive to death loading in a bunch of crap from the harddrive to fill your memory that you may never use.
If you have say 3gb of RAM, every time you reboot your machine, it will try to load in 3gb of data to fill all this memory… in the background, even if you are trying to work. This is a pain esp if your work is harddrive intensive… you will burn up your harddrive with the accessing. Your best bet is to walk away and let the system calm down, load in all the bullshit.
The bad part of superfetch, is a soon as you close a big application (say a game, or gimp, or other program that uses a gigabyte of RAM), superfetch will immediately start grinding away at the disk to make use of this memory.
Yeah, you get a boost by having all your RAM used as a cache, but the down side is, a LOT more wear and tear on your harddrive with a bunch of unnessary loading of ‘guessing what data may be used in the future’ which may or most likely won’t be used. Windows engineers decided… we don’t care about users harddrives, as long as we can make this dog look and run better, screw it.

if you attempt this, you are a complete idiot. its nice to know how, yeah, but superfetch is extremely useful to vista performance. indexing is one thing, you dont really need it if you dont search for stuff, but disabling superfetch is like disabling your page file/virtual memory.
it only causes instabilities.
