We've upgraded CDXZipStream to increase the speed and performance of the CDXZipCode and CDXDistance functions. Caching is now employed so that repeated calls to the same Zip Code will come from memory and not the external database. This provides an order of magnitude performance increase. This is important when doing repeated operations such as a distance matrix or retrieving multiple data items from a single zip.
To get this new feature you need to install CDXZipStream version 126.96.36.199 or better which is the current trial version on our site. There is no cost to get access to the update. The installation file for this can be downloaded here.
