Another must read white-paper: Analysis Services 2008 R2 Performance Guide.

This white paper describes how business intelligence developers can apply query and processing performance-tuning techniques to their Microsoft SQL Server 2008 R2 Analysis Services OLAP solutions.  It applies to SQL Server 2005, SQL Server 2008, and SQL Server 2008 R2.

This is an update and expansion to the previous performance guide white-paper, which was published three years ago, and which only applied to SQL Server 2008.  There are about 30 new pages of new content.

If you are working with SSAS, you have to add this to your “to read” list and make it a high priority.
