Who should use O&O CleverCache?

O&O CleverCache is a tool for gaining control over the system cache. Windows XP, Windows 2000, and Windows NT have built-in file cache management. When files are accessed on secondary media (e.g. hard disk),  Windows "swaps", or copies, those files from the secondary medium to main memory. Since main memory can be accessed much faster than a hard disk, file caching is designed to accellerate system performance.

A Little Information on the File Cache in Windows XP/2000/NT

Windows XP/2000/NT is not so efficient, however, when managing the file cache on its own. It allocates main memory for the file cache even when it is no longer available for running applications. If applications request new memory, the system is forced to swap out segments of memory into the paging file located on the hard disk, requiring time-consuming read/write access. Paradoxically, in this situation file caching, meant to improve system performance, actaully leads to a dramatic decrease in system performance by acting as a speed brake for your computer. This is where O&O CleverCache V6 comes in and solves this problem by instituting it own smarter cache management system. You can find more information on the functionality on our O&O CleverCache product information page.

Applications
1. The "Server" Phenomenon
If you use an XP/2000/NT-Server for days, weeks, or even months at a time without interruption, slower answering times of applications will occur. By restarting the server, you will find out, even with out running a disk defragmentation, that the system runs with significantly higher performance. the reason for this is the empty file cache resulting from the reboot of the system. O&O CleverCache achieves the same result without any reboot, ensuring that maximum performance while the system is online.

2. Working with large files
System activities that require the constant accessing of files on the hard disk can be susceptible to performance losses due to inefficiency in the way the file cache operates. Particularly when using applications that require a large amount of memory, it is recommended that you try out O&O CleverCache on your system. Desktop Publishing and graphical applications, CAD and video capturing applications are typical examples for such applications. To see exactly how much O&O CleverCache V6 can help, please try the following: After the trial software has been installed onto your computer, right click the icon in the task tray to activate the context menu. Then select the heading "Agent" and then "Pause". Compare the performance of your system before and after O&O CleverCache V6 has been activated.

3. Utilizing and switching between multiple applications
Multitasking is commonplace in Windows. Users will minimize an application windows to the task tray and leave it to run in the background while another application is in use. This is especially the case with users of Office applications who often switch between different Office applications at a high frequency. But even if the application is minimized it still continues to use main memory resources, possibly consuming file cache resources as well. Using O&O CleverCache V6 significantly reduces the cache resources and thus increases available main memory resources. This results in much faster response times for the active applications.

4. System alert: No virtual memory available
Getting the message from your system that no virtual memory is available means that you are running applications that require too much of your memory resources. O&O CleverCache V6 can help by regulating the file cache and giving back more main memory resources to your system.

5. Server with critical business data
In addition to its wide range of features, O&O CleverCache V6 provides you with increased data security with the Mem-O-Safe feature. This technology gives you control over the update interval of the file cache. The file cache in Windows XP/2000/NT is not only used to read data from, but also to write data to the hard disk. To increase system performance saved data, data is not immediately written to the secondary media (hard disk), but buffered in the internal file cache. The system waits to see if more data has to be written on the hard disk. Depending on the system load, Windows sets the update interval for the file cache between 4 and 15 seconds. If during this period a system failure occurs, all data that has not already been written to disk is lost. Critical data may be lost, sometimes necessitating reinstallation. This situation often occurs during a power failure, user error, or a system crash ("Blue Screen of Sudden Death"). Mem-O-Safe technology lets you control and configure the update interval of the file cache on important file servers, for example, to minimize possible losses of data. The configuration of the interval can be changed through the O&O CleverCache V6 applet found in the Control Panel.
