In this white paper we discuss two of the new features in SQL Server 2008, Star Join and Few-Outer-Row optimizations. We test the performance of SQL Server 2008 on a set of complex data warehouse queries designed to highlight the effect of these two features and observed a significant performance gain over SQL Server 2005 (without these two features).
