Please disregard the previous post. I still have a performance issue but it is not related to Role Based security

I've been having performance issues with Report Sharpshooter when using a BBS as a datasource (see http://forum.strataframe.net/Topic20268-14-1.aspx). I was putting together a small test app and couldn't reporduce the performance issue until I noticed that my test app was a standard SF application without security. When I put together a test using a SF app with security, the performance issue was back. It would appear that there is something going on when Role Based security is added that impacts the rendering time for Report Sharpshooter. Are there any BO properites that I should be setting in this situation?
