INF: sp_configure Parameters Affect Memory Usage by SQL Server

ID Number: Q61792

1.11 4.20

OS/2

Summary:

There are certain parameters (for example, sp_configure parameters)

that affect 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
