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: As a conclusion, when executing stored procedures that only return update counts output parameters will be available immediately, as jTDS will process and cache the whole response.

This parameter is lastUpdateCount and you can find out more about it here. In our oppinion this is better than having a benchmark of our own, which could be designed in such a way as to give jTDS the edge.
