There are certain parameters (for example, sp_configure parameters) that effect the minimum amount of memory required by SQL Server. You should be aware of their effects on memory, and set the values only as high as needed. This will conserve memory, making more memory available for cache, and improve performance.

Below are the relevant parameters for SQL Server version 4.2. This information is also applicable to versions 1.1 and 1.11; however, the devices parameter is not used in those versions.

  Parameter           Value -          -   user connections    37K per user

locks              32 bytes per lock (1000 locks costs about 32K)

open objects       70 bytes per object (100 objects cost about 7K)

open databases     About 1K (908 bytes) for each

devices            About 41,400 bytes (21 pages) per device

Additional query words: 4.20
