Here is the Docker image for the geocoding stack that foursquare uses, with all world data already set up (would take you about a day to set up yourself):

Why does it take so long?

Processing the raw data and generating a search index is quite resource (IO/RAM/CPU) intensive. Some geocoders (not twofishes) need 100GB of raw data.
