My MapInfo .mif/.mid import takes a very long time. Whats up?
– The short answer is that Manifold’s mfd/mdb format is a pre-compiled format that takes a long time to create the first time; however, every time you work with the resultant Manifold files the work goes much faster. We think this is a smart tradeoff. See the Importing MapInfo .mid/.mif Files page for a longer discussion.
