Configuring SQL Server .NET Data Provider Connection Pooling
You can configure connection pooling by using a set of name-value pairs, supplied by means of the connection string. For example, you can configure whether or not pooling is enabled (it is enabled by default), the maximum and minimum pool sizes, and the amount of time that a queued request to open a connection can block. The following is an example connection string that configures the maximum and minimum pool sizes."Server=(local); Integrated Security=SSPI; Database=Northwind;
Max Pool Size=75; Min Pool Size=5"
When a connection is opened and a pool is created, multiple connections are added to the pool to bring the connection count to the configured minimum level. Connections can be subsequently added to the pool up to the configured maximum pool count. When the maximum count is reached, new requests to open a connection are queued for a configurable duration.
