O&O CleverCache V6 is a unique tool to optimize the File Cache Management of Windows Vista, Windows NT, Windows 2000, and Windows XP. This results in an enormous performance boost and may double the original system speed - without any new hardware and without restricting your system's stability. Simply install O&O CleverCache V6 Pro and you are ready to go! Neither configuration nor rebooting is needed. Within 5 minutes, you activate unused resources of your Windows Vista/NT/2000/XP system! The more the file cache grows, the less memory is available to running applications. The result is a significant performance loss, as requests for memory can lead to the so-called "swapping", i.e. currently unused memory areas are paged out to Vista/XP/2000/NT's paging file. O&O CleverCache V6 Pro takes over control of the resource management for file caching and applications. It prevents heavy system loading and guarantees the availability of a certain amount of memory. This leads to a performance increase and to lower response times, especially if you are running many applications at the same time and tend to switch between them quite often.
