A unique tool to optimize the File Cache Management)

O&O CleverCache V4 is a unique tool to optimize the File Cache Management of 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 V4 Pro and you are ready to go! Neither configuration nor rebooting is needed. Within 5 minutes, you activate unused resources of your Windows NT/2000/V4 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 XP/2000/NT's paging file. O&O CleverCache V4 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.
