I've been seeing all praises for the application called SuperFetch that makes launching and using applications faster, and never slower, which is definitely beneficial for someone who uses the computer for long periods of time.

For example, http://www.osnews.com/story/21471/SuperFetch_How_it_Works_Myths:

Contrary to what many Windows tweaking guides on the internet tell you, SuperFetch does not impact your every day computing experience in a negative way. SuperFetch makes often-used applications load fast - it doesn't make other applications load any slower. As such, turning it off, as some guides advise you to do, can only result in a slowdown, not a speed up.

I believe that most things have both advantages and disadvantages. Now I've read through a couple of articles but have not found any talking about any disadvantages SuperFetch has, so basically I was wondering what disadvantages does SuperFetch has? Is it really as good as it is purported ?

I don't understand what's wrong with this question. How may it be rephrased to apply for reopening? –  Pacerier Sep 14 '11 at 6:13

I've found the answer: Once the map is loaded and you join the game, the entire game is in memory. What could possibly be loading from disk at that point? Well, SuperFetch saw a ton of memory freed to make room for the game, and dutifully went about filling the leftover free memory on a low-priority background disk thread. Normally, this would be no big deal, but even a low-priority background disk thread is pretty noticeable when you're playing a twitch shooter online with 63 other people at a resolution of 1600x1200. >> voting to reopen to submit this in it's proper place. –  Pacerier Sep 16 '11 at 9:20
