Identifying and Resolving MDX Query Performance Bottlenecks Whitepaper

Performance is the most common incentive for using Analysis Services. Yet, despite the advances in the SSAS management tools, optimizing the MDX query performance is still considered as “black magic” by many.

Now that SSAS Designer supports DAX queries, we should be able to do everything we were able to do in MDX, right?
