| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1 | Windows 2000 Professional: 0 Windows 2000 Server: 1 |
Determines whether the system maintains a standard size or a large size file system cache, and influences how often the system writes changed pages to disk.
Increasing the size of the file system cache generally improves server performance, but it reduces the physical memory space available to applications and services. Similarly, writing system data less frequently minimizes use of the disk subsystem, but the changed pages occupy memory that might otherwise be used by applications.
| Value | Meaning |
|---|---|
| 0 | Establishes a standard size file system cache of approximately 8 MB. The system allows changed pages to remain in physical memory until the number of available pages drops to approximately 1000. This setting is recommended for servers running applications that do their own memory caching, such as Microsoft SQL Server, and for applications that perform best with ample memory, such as Internet Information Services. |
| 1 | Establishes a large system cache working set that can expand to physical memory, minus 4 MB, if needed. The system allows changed pages to remain in physical memory until the number of available pages drops to approximately 250. This setting is recommended for most computers running Windows 2000 Server on large networks. |
Caution
Setting this value to 1 can have an impact on the performance of any services that run on the server. A value of 1 should be used only if the server is used exclusively as a file server.
