The document discusses the challenges of performance testing elegant websites. Parameterization and correlation are important for scripting tests with multiple users and sessions. The authors developed a scripting engine to help with parameterization, correlation across builds, and porting scripts. While it helped reduce time, cost and improve quality, further enhancements are needed to better handle large sites and business logic.
