I have millions of addresses that I want to geocode and I can do that in ArcGIS but it would take me endless number of hours. Is there a faster method that you can recommend?
I geocode millions of records all the time. The best method I have found, is to split the file into subsets so as to not run into 'out of memory' errors.
Also, right click your locator, and click properties. There is a 'performance' section, cranking up the 'Data cache size' speeds up geocoding immensely, same with 'Number of threads'. But make sure not too set it too high or memory issues ensue.
