Guys, this may seem like a really silly question but please bear with me.

Context:
We are attempting to run several tests on various SQL Server databases. We are in the process of developing a test plan to determine what we test and how we go about testing it.

Any thoughts/ideas would be appreciated.

I'd start with comparing execution plans. If they differ, you know at least one place to look
further.

Also, yes, there is overhead with displaying the result in SSMS. I suggest you try the option "no
output" (or something like that, check under Tools, Options in SSMS for the setting).

If both above doesn't give anything, you probably want to use Profiler and see if there is some
significant events produced in one but not the other environment.

Context:
We are attempting to run several tests on various SQL Server databases. We are in the process of
developing a test plan to determine what we test and how we go about testing it.

We've written some C# code to perform several queries on the database. We took one of the code tests
and essentially reproduced it in the form of a SQL script (in an attempt to determine if it was
better to write our tests as C# code or TSQL Scripts). Strangely enough the execution time of the C#
code is tremendously faster than the TSQL script run from Management Studio. Mind you, all we're
doing in the script is executing a SPROC in a loop (same as the code). What would be the cause of
this difference? Would it be the fact that results are displayed in the Management Studio results
windw in real-time? or should I simply just profile the database and see whats happening in both
cases?

Any thoughts/ideas would be appreciated.
