The first thing is: Don't do it.

You may get away with it for a project, but SQLServer connections are scarce resources in the real world, and any app holding a connection open globally will seriously annoy database administrators as the connection is not available for other users - this gets expensive!

Always create connection, use connection, close and dispose connection as quickly as possible.

Are you sure it is the connection that is taking time, not your command?

Use Class and create a public function for creating data connection
here is the code

C#

public bool OpenConnection(MySqlConnection Conn)
    {
        String connStr = "your connection string"
        if (Conn == null)
        {
            errorMessage = "Connection Object doesn't exists. Internal Error";
            return false;
        }
        if (Conn.State != ConnectionState.Open)
        {
            try
            {
                Conn.ConnectionString = connStr;
                Conn.Open();
                return true;
            }
            catch (Exception objE)
            {
                
            }
        }
        else
        {
            return true;
        }
    }
