Unlike its predecessor versions, R9 mart is known for its quick performance, even over a Wide Area Network (WAN). This document provides a sampling of performance metrics of the CA ERwin Data Modeler r9 Workgroup Edition compared to version r8.2.5, in particular environments. Tests were run using both SQL Server 2008 and Oracle 11g in the following environments hosting the three-tier architecture: across a WAN, across a LAN, and hosted on the same machine. Tests were performed for the following actions: Mart Model Save, Mart Model Open, and Incremental Save.
