As a general principle we try and keep synchronization to a minimum both for performance and deadlock reasons. When executing a stored procedure or any query, for that matter the response from the SQL Server is serialized in the same order it is executed in: The exception is thrown because it’s better to warn the user that the output parameters are not yet set instead of leaving the impression that all is ok and cause other, harder to detect problems.

So for procedures returning ResultSet s you will have to loop, consuming all results before reading the output parameters i. This is jyds if say you are querying a stored procedure that creates a temp table, runs updates against it and then returns the table as a result set.

Or even better, a benchmark I can run myself?
