Faster XP/2003/Vista Boot and Application Launch with Prefetch Manager!<a href='http://www.hs-lab.com/products/sp/'>Software home page</a><a href='http://www.hs-lab.com/downloads/hslab-prefetch-manager.exe'>Software download</a>Windows XP has a Prefetcher component, which shortens the amount of time it takes to start Windows and programs. When trouble shootingeither Windows or program start-up issues, it might be helpful to disable the prefetcher using HSLAB Prefetch Manager, because it runs as abackground service while ather applications are running or loading.When a Windows XP system is booted, data is saved about all logical disk read operations. On later boots, this information is used to prefetchthese files in parallel with other boot operations. During boot and application launch, a Windows system demands and pages a sizable amountof data in small chunks (4 KB to 64 KB), seeking between files, directories, and metadata. The Logical Prefetcher, which is new for WindowsXP, brings much of this data into the system cache with efficient asynchronous disk I/Os that minimize seeks. During boot, the LogicalPrefetcher finishes most of the disk I/Os that need to be done for starting the system in parallel to device initialization delays, providing fasterboot and logon performance.Logical prefetching is accomplished by tracing frequently accessed pages in supported scenarios and efficiently bringing them into memorywhen the scenario is launched again. When a supported scenario is started, the transition page faults from mapped files are traced, recordingwhich page of a file is eccessed. When the scenario has completed (either the machine has booted or the application started), the trace ispicked up by a user-mode maintenance service, the Task Scheduler. The information in the trace is used to update or create aprefetch-instructions file that specifies which pages from which files should be prefetched at the next launch.
