SSMS returns results immediately; ADO takes longer

I am running a query that returns ~250k results.

• It is basically SELECT * FROM my_schema.my_view (and the view is somewhat complex, and all table references in it are two-part)


• I am not passing any parameters


• I have tried setting ARITHABORT to ON and using OPTION (RECOMPILE)


• Within 2 seconds of executing, SSMS has returned ~23k results


• SSMS takes ~1m to return all ~250k results


• With ADO and the same query, it takes ~1m to obtain the first result from the DataReader


• PARAMETERIZATION is set to SIMPLE

I have read http://ift.tt/V20pUB and about a couple dozen other SO/DBA answers trying to make sense of this but I just can't seem to get my results streaming any faster. It almost seems like when I use ADO, SQL Server tries to store all of the results in a temporary table before returning.

What else can I check or try to get my results streaming immediately like they do in SSMS?
