Different Engine. Mondrian cubes come from Pentaho. A ROLAP cube won't necessarily give you an immediate huge improvement - what is it you're looking for? The main advantage of cubes is caching ( which will obviously help - but no use when cold ) and ability to process the data in a businesslike way.
Saying that Mondrian is very good and has a lot of performance related features - especially agg tables.. Mondrian is also used in a lot of other BI suits and follows industry standards ( olap4j/mdx/xmla etc)
Perhaps if you have a specific data problem more info on that could help devise a solution!
You may also want to look at an analytic db, combine Mondrian or any cube with one of those and you'll fly.
