title: SqlClient.SqlDataAdapter.Update() Performs Very Slowly
body: <p>I am porting VB.Net 2 code (VS 2005) to VB.Net 4 (VS 2010).  So far things have been going relatively smooth.  However, in testing my new ported code, I came across a strange behavior. </p>
  
  <p>In VS 2005 (.Net 2), I have a DataTable filled with data.  I then use a DataAdapter to send updates back to the SQL Server.  When I perform the  SqlClient.SqlDataAdapter.Update() command, it execute in roughly 4 seconds.  The same code, on the same table in VS 2010 (.Net 4) runs in 1 Minute 17 Seconds.  This is completely unacceptable.  However, I have no clue as to <em>why</em> it is happening.  The .Update() method is an internal command, not one that I modified in any way.  It does not error out, it's just painfully slow.</p>
  
  <p>Anyone have any ideas?</p>
