In one particular scenario, while debugging of the code, it appears to take 3 seconds after exiting the service call, to when the SQL is issued to the database. The SQL call within the database is in most cases under 100 milliseconds, so it appears like the framework is taking a large amount of time to prepare the statement.  </p> <p>Thoughts?</p> ( John) http://www.silverlightshow.net/items/Ian-Burt-on-performance-issues-with-RIA-services-and-a-bit-more.aspx Fri, 18 Dec 2009 20:36:06 +0300
