The reason it takes so long (15-20 seconds) for maps to load (and refresh the cache) is that Tableau loads a nifty DB file named GEOCODING.fbd which contains ALL the geocoding data for the entire world! OK, maybe not all, but it loads/sort/queries a heck of a lot of records just to give you a representation of your little hometown set of ZIP codes.

So here's the little IDEA: Let us 'extract' the data relevant to our map view (just like the data-source extract works) so we trim the massive DB down to a zippy size. And we (or worse our clients) don't have to stare at a 'calculating view' dialog box for eternity (OK only 15-20 seconds, but that is an eternity to a speed-freak!)
