What is the maximum and minimum size of connection pool ADO.Net Supports in the connection string.
Min Pool Size=[max size ?]
Max Pool Size=[min size]
回答1:
There is no documented limit on Max Pool Size. There is however an exact documented limit on maximum number of concurrent connections to a single SQL Server (32767 per instance, see http://msdn.microsoft.com/en-us/library/ms143432(v=SQL.90).aspx).
A single ADO.NET pool can only go to a single instance, so maximum effective limit is therefore 32767.
Min pool size is zero
回答2:
Default Max Pool Size 100
Min Pool Size 0
Connection Pooling for the .NET Framework Data Provider for SQL Server
回答3:
Default value of max pool size is 100 and min pool size is 0
回答4:
The Default Connection Pool Size is 100 . You can increase the pool size using 'Max Pool Size' property in the connection string. for example - Max Pool Size=1000;
If you are using the Azure SQL server, the number of concurrent connection will depends on SQL Server Tier that you are using.
