Most modern database-backed web applications are built upon Object RelationalMapping (ORM) frameworks. While ORM frameworks ease application development byabstracting persistent data as objects, such convenience often comes with aperformance cost. In this paper, we present CADO, a tool that analyzes theapplication logic and its interaction with databases using the Ruby on RailsORM framework. CADO includes a static program analyzer, a profiler and asynthetic data generator to extract and understand application's performancecharacteristics. We used CADO to analyze the performance problems of 27real-world open-source Rails applications, covering domains such as onlineforums, e-commerce, project management, blogs, etc. Based on the results, weuncovered a number of issues that lead to sub-optimal application performance,ranging from issuing queries, how result sets are used, and physical design. Wesuggest possible remedies for each issue, and highlight new researchopportunities that arise from them.
