Specifying packet size using SqlConnection

Connection string

This .NET Framework Data Provider for SQL Server connection string can be used for connections to SQL Server 2019, SQL Server 2017, SQL Server 2016, SQL Server 2014, SQL Server 2012, SQL Server 2008, SQL Server 2005, SQL Server 2000 and SQL Server 7.0.

Server=myServerAddress;Database=myDataBase;User ID=myUsername;
Password=myPassword;Trusted_Connection=False;Packet Size=4096;

By default, the Microsoft .NET Framework Data Provider for SQL Server sets the network packet size to 8192 bytes. This might however not be optimal, try to set this value to 4096 instead. The default value of 8192 might cause Failed to reserve contiguous memory errors as well, read more here.
