Just seen this interesting post on the SQLCat blog containing MDX tips, most of which I'd not heard about:
http://blogs.msdn.com/sqlcat/archive/2006/10/12/best-sql-server-2005-mdx-tips-and-tricks-part-1.aspx

I would be careful about taking them all as general rules though. I ran into the issue described about calculated members using ParallelPeriod vs hard-coded tuples earlier this year on a performanve tuning job, but couldn’t repro it in AdventureWorks or any other cube so I guessed it wasn’t as straightforward as it seemed and therefore didn’t blog about it; I suspect some of the others aren't generally applicable either (I checked with higher authority and he agreed). That doesn't mean they won't be worth trying if you do have performance problems though.
