I would suspect your connection isolation level to be more intrusive than the one SSMSexp uses (read committed).
What isolation level are you using ?

Please check the database properties, using SSMS, and see if the Auto Close open is set to "YES" or "No".
Do you measure performance in SSMS when you click the Execute command, and measure that against when your VB6 application has a command button clicked? Remember when using SSMS you have opened a connection to the server/db, and if your Auto Close option is set to "Yes" than your VB 6 application has to open the connection as well as execute the procedure and that alone could account for the difference in performance that you are reporting.

hi
Auto close is ture.
when i work with the vb6 application and ssms-->new query on the db
is open ,with out any commant in the query page. just open th query page.
the vb6 application work very well.
when i closed the query page
then the vb6 application works very slow .
at 5 times slower.
this is the syptoms of the problem
i did not know what the connection between the ssms and the performance of the application
best regards and thank you
