Unanswered: Hyperion Essbase or MS Analysis Server
i'm wondering if anyone has any experience with both Hyperion Essbase and MS Analysis server. I'm working for a company which currently uses Essbase OLAP server 6.1, but they're not satisfied with it's performance. They're now considering MS Analysis server. What are your findings? Performance is most important, but ease of use and other findings are usefull.
