The Multiple Mirror Telescope (MMT) serves a dual function. It is a very large astronomical telescope with state-of-the-art instrumentation which is now being used for 85% of the time for astronomical research. It fills an equally important function as a testbed for new concepts in making large aperature telescopes at a modest cost. The MMT outperforms other telescopes in a number of areas, thus making it the benchmark against which future astronomical facilities will be measured. This paper summarizes the performance of the MMT.
