I've seen it pop up on my computer from time to time when I've been away from the keyboard, but the instant I start doing something such as moving my mouse , the process stops whatever it's doing and gives back the resources it was using. . I'm surprised that neither my old Vertex over many firmware revisions Rollseyes , or my Intel 320, indentify themselves. It doesn't sound like that is some magical feature that is the sole cause of your problems. If you had to do the 3 optimizations i mentioned manually, it takes less than a minute. It does this in the background and stores the pre-fetched files in unused memory. Hope this info is of use to someone.
I recommend it's on because 99% of the time that's what it does. Didn't seem to fix my problem though. So if you watch video in the evening then it may prefetch your video player at that time, but not bother doing this at lunch time. Please don't talk about things you clearly don't understand. It also analyses some usage. When you launch the application, it will start faster — your computer reads its files from memory, which is faster, instead of from disk, which is slower. My problem is the misconception that Superfetch is useless from the get go that many arm chair system admins and journalists seem to spread like he did.
And Windows Update if it thinks is a good idea to use your bandwidth and disk while you're playing. Disabled it and disk usage dropped for a little while, but the problems came right back. It is useful in areas where the applications you run day to day never change and the first three days of the life of a Windows installation, Superfetch is enabled but not active and instead learns what apps you open. Both times this was fixed by turning off superfetch and prefetch, so there are times that they can impact performance. These days the only effect I notice from superfetch is slightly faster load times, I don't observe any framerate drops that could be tied to it.
Tl;Dr there is clearly a larger, and potentially more serious, issue here that Superfetch just happens to exacerbate. The best I can offer you is information about what Superfetch is and how it functions so that you can make an informed decision for yourself. I turned it on to see if it really was the main reason my notebook couldn't even have a browser and a fucking minecraft game open at the same time and it really was, after turning it on again and restarting the pc it was slow and laggy again. Take a look at my original comment again and it clearly says at one point. I did read about it recently. There should be no other ill effects. So don't worry about the memory use.
Now, when you return to your desk, your programs will continue to run as efficiently as they did before you left. What I actually said is if you find it faster with it off then keep it off. Its Windows way of making things easier for users. It tends to not work well with gaming, but can improve performance with business apps. However if you find performance actually improved then go ahead and keep it turned off. Also I wasn't aware that it would turn off Superfetch if needs be.
I bought a new laptop, and I has used it for 2 month for the schoolwork and for gaming for a while , and the ram level has reached about 56% to 62% and disk always 100%. It doesn't do anything else. Post a screenshot of that disk tab. When Windows Vista was released, , and the results of their benchmark were informative. Maybe it is a bug, but why bother turning it on just because? Generally I would say never turn it off. Thanks, Jack Jack Microsoft Answers Support Engineer Visit our and let us know what you think. The memory usage is a non-issue because it only uses unused memory so no cost there , and when something else needs that memory it'll just get free'd up.
If not then forget about it. It works alongside the disk defragger, perhaps this is a sign that your drive is fragmented? It's just a service that is either on or off, and now it's off. This truly is a personal preference question. It is a process that happens over time , so the instances of it fetching would reduce and increase performance over time. If Windows determines that it isn't needed or shouldn't be used, it will disable the service itself and I'm guessing it did that in your case. Windows SuperFetch prioritizes the programs you're currently using over background tasks and adapts to the way you work by tracking the programs you use most often and preloading these into memory. Windows would see that I would load WoW at a certain time almost every day, so it would start preloading it around that time.
What exactly is using up all your disk resources? Windows Search and indexer are also big enemies of gaming. All modern operating systems have some kind of prefetching of files and it does give you real speedups. With SuperFetch, background tasks still run when the computer is idle. I told you what it does. They may have fixed some of the issues since the older implementations, for example it claims that the SuperFetch loaded ram is low priority, but I don't think it will de-allocate it until it has finished the inital allocation which causes problems with large programs but not small ones.
ReadyBoost was introduced in Windows Vista, where it was a heavily promoted feature. Nothing is being installed or removed. I hope this information is helpful. This was when I only had 8gb of ram, and quickly started paging my X3 game to disk. Enable or disable the Windows 10, 8, or 7 Superfetch otherwise known as Prefetch feature. There should be no other ill effects. Most people simply disable superfetch to fix this, and while it fixes things, they don't necessarily understand why.
