MAPI Messaging Benchmark (MMB3/MMB4) has been the benchmark for measuring the performance and scalability of computers running Microsoft Exchange Server. While MMB has served its purpose, it also has limitations in helping our customers compare solutions. Among the most significant limitations, MMB does not take into account variation in end-user usage profiles, modification and updates to storage solutions, differences in customer topologies, and impacts of other features or applications on performance. MMB compares single servers, but does not compare solutions.
As the era of benchmarking changes to adapt to different types of clients, user profiles and other variables, the current methods are becoming impractical. With that said, Microsoft will be closing down the MMB3 site as well as the Performance Benchmark result site, in the first quarter of 2008. Although the MAPI Messaging Benchmark results will not be posted by Microsoft, we will continue providing the tools necessary to allow Microsoft partners to perform their own performance and scalability benchmark analysis for Exchange Server. These tools include: Exchange Server JetStress, Exchange Load Generator, and Exchange Server Stress and Performance (this tool is in the process of being merged into LoadGen).
In place of the current MMB3 site, we will work with Partners to provide links to their respective sites where customers can find real world performance and scalability studies which assess actual customer scenarios and solutions.
