Default Client Connection Behavior
After installing SQL Server Native Clienton a client computer, the client is immediately ready to connect to an instance of the database engine. In most cases, a SQL Server client does not need any special configuration to connect to an instance of the Database Engine.

Geo-Replication Performance Gains
Extensive replication performance testing compared SQL Server 2005 running on Windows Server 2003 against SQL Server 2008 running on Windows Server 2008. Both operating environments replicated data between a server located in Tukwila, Washington, and another located in Blueridge, Virginia—a distance of approximately 3,000 miles. The results show that SQL Server 2008 running on Windows Server 2008 yielded up to 100 times faster performance without requiring any expensive wide area network (WAN) acceleration hardware.
