Check List for Performance Optimisation in SQL Server Analysis Service 2005
Introduction
No matter what your platform or the tools that you are using, performance is almost always the number one feature that customers require. In the case of SQL Server Analysis Service (SSAS), there are four areas where we can improve the performance. They are database design, processing, querying and configuring SSAS.
Key Attribute
For each dimension, there should be a key attribute. If you have a choice between selecting a key attribute from an integer or varchar you should select an integer column as your key attribute. Allocating an integer column as a key attribute not only improves the query performance but also requires less storage. If you include an integer as the key attribute, then you need to have an integer column for the FACT table to link with dimension table. This will again assist to improve the query performance.
