World's Fastest Geocoder

Appistry Demonstrates World’s Fastest Geocoding Solution at GEOINT 2007 Symposium ESRI ArcGIS-Based Geocoder Running on Distributed Platform Powered by Appistry Achieves 40,000 Geocoding Transactions per Second San Antonio, Texas (GEOINT 2007 Symposium) October 22, 2007 – Appistry today demonstrated the world’s fastest commercially available solution for high-volume geocoding at the GEOINT 2007 Symposium in San Antonio, Texas. Geocoding is the process of resolving geographic place names, addresses or other data to geographic coordinates or geocodes, and is a foundational process for both commercial and government users of geospatial data. The demonstrated solution utilizes Appistry Enterprise Application Fabric (EAF) to provide scalability and reliability for a geocoding application based on the industry-leading ESRI ArcGIS 9.2. The geocoding application was developed in hours using ArcGIS, and designed to run on a single computer. Appistry EAF allowed it to be quickly and easily scaled-out across 16 dual-CPU servers. “With the explosion in available geospatial data, the ability to quickly manipulate it in high volumes has never been more crucial,” says Chris Cappelli, director of sales, ESRI. “Appistry’s ability to take ArcGIS-based processes and easily scale them across many computers creates exciting new opportunities for organizations that depend on geographic information.” Presented with 1.5 million randomly selected US addresses distributed across 50 states, the distributed solution bulk-coded the addresses in just over 30 seconds. The average rate demonstrated was in excess of 40,000 geocoding transactions per second. Moreover, because the system’s geocoding performance scales linearly as additional computers are added, it is capable of meeting any level of demand. Read more (GIS User)...

What type of accuracy is being provided? I can't imagine a geocoder archiving that type of speed to return quality information. Does anyone have statistics on the number of false positives or city and county centroids it is returning when an address is not found on the first pass? Speed is impressive but without accuracy this is just a parlor trick.
