Visual Studio 2008 -- Speed Testing Tools ?

Does anyone have testing tools to see
the amount of time an applications take ?
----------------------------------------------
Example:

I have a form that displays 200+ results,
users change about 10 results, and click
submit.

I want to see how much time and network
traffic it takes to see which option
is better.

  Option #1: letting Microsoft's
             TableAdapterManager
             take care of the update or

  Option #2: writing changes to a temp
             table and passing changes to
             a storedproc one at a time
