But advanced users with non-standard drive configurations, or those running Windows in virtual machines, may want to exercise manual control over these important services. The default value is 3 setting it to 0 will disable Prefetching.Īs mentioned, most users do not need to adjust Prefetch/Superfetch settings, and setting incorrect values can increase boot and application launch times significantly. You can configure Prefetch in one of four ways by entering the corresponding number in the Value Data box:ġ – Enables Prefetch for Applications onlyģ – Enables Prefetch for Boot and Application files On the right side of the window, double-click on EnablePrefetcher. Just as before, you can also launch the Registry Editor by searching for regedit on the Start Screen.įrom the Registry Editor, navigate to the following location: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlSession ManagerMemory ManagementPrefetchParameters Launch the Registry Editor by right-clicking on the Desktop Start Button, choosing Run, and typing regedit.

Close the Services Manager and reboot to have the change take effect.Īfter you disable Superfetch, you can disable Prefetch from the Windows Registry. This will kill the service for now, but it will restart automatically at next boot unless we tell it not to.

Double-click Superfetch to launch its Properties window and click on Stop to stop it. Click Apply and then OK to save your changes. In the Services Manager, scroll down to find Superfetch, which is controlled by the Windows service called SysMain. Under the “Startup Type” drop down menu, select Disabled. What Does Readyboost Do ReadyBoost enables NAND memory mass storage CompactFlash, SD card, and USB flash drive devices to be used as a cache between the hard drive and random access memory in an effort to increase computing performance.ReadyBoost relies on the SuperFetch and also adjusts its cache based on user activity. In the Services Manager, scroll down to find Superfetch, which is controlled by the Windows service called SysMain. Alternatively, you can search for services.msc from the Start Screen. To manually disable Superfetch in Windows 8, launch the Windows Services manager by right-clicking on the Desktop Start Button, choosing Run, and typing services.msc. This most often occurs with non-standard configurations such as fast RAID arrays of HDDs, or mixed use of both SSDs and HDDs.

While most users will be fine letting Windows decide how to use Superfetch and Prefetch on its own, there are situations in which Windows may make the wrong decision, and power users will want to manually disable or enable the services. In Windows 8, however, the operating system tries to analyze the performance characteristics of the system’s storage and intelligently enable or disable Superfetch/Prefetch as needed. In Windows 7, Microsoft attempted to address this issue by automatically disabling Superfetch and Prefetch when a fast SSD was detected. While essential to ensuring a smooth user experience in systems with traditional hard drives, some systems with solid state drives may not see much benefit thanks to the SSDs’ inherent performance advantage, and Prefetch/Superfetch services may actually be detrimental to SSDs in the long run due to the unnecessary writes they generate. Prefetch and, since Windows Vista, Superfetch, are technologies in Microsoft Windows that can significantly improve system resposiveness by predicting which applications a user is likely to launch and preemptively loading the necessary data into memory.

The recommended amount of flash memory to use for Windows ReadyBoost acceleration is one to three times the amount of random access memory (RAM) installed in your computer.How to Disable Superfetch and Prefetch in Windows 8 On Windows 7, the largest cache file size is 256GB (can span up to 8 flash drives). On Windows Vista, the largest cache file size is 4GB

The device must have at least 235MB of free space

The device must be capable of 2.5 MB/s read speeds for 4 KB random reads spread uniformly across the entire device and 1.75 MB/s write speeds for 512KB random writes spread uniformly across the device The capacity of the USB flash drive must be at least 256MB (250 after formatting). SOAP makes use of an XML knowledge format to declare its request and response messages, counting on XML Schema and different applied sciences to implement the construction of its payloads. The device should have an access time of 1 ms or less. What Is A Soap Request SOAP is the Simple Object Access Protocol, a messaging commonplace outlined by the World Wide Web Consortium and its member editors.

This allows Windows Vista or Windows 7 to service random disk reads with performance that is typically 80-100 times faster than random reads from traditional hard drives.įor a USB flash drive to be compatible, it must conform to the following requirements: ReadyBoost is a feature of Windows Vista and Windows 7 that uses a USB flash drive for caching.
