title: SSIS Designer is running VERY slowly
body: <p>I am developing an SQL Server Integration Services package.  I have been doing some major refactoring to this package, and now the designer is running really slowly.  Even moving components around the screen causes the designer to hang for 2-3 minutes.  Looking at the task manager Visual Studio is consuming around 80% of the CPU during this period.</p>
  
  <p>Does anyone have any ideas about this slow performance?</p>
