Overview
Application performance Review (also known as Application Performance Walkthrough or Application Performance Assessment) is the process of review of an existing application (in production) to evaluate its performance and scalability attributes. The performance characteristics of the application are determined by its architecture and design. Applications must be architected and designed with sound principles and best practices. No amount of code fine-tuning can disguise the performance implications resulting from bad architecture or design decisions. Performance reviews let all stakeholders realize where they stand and take appropriate decisions.

Performance and Scalability
Performance and scalability are two quality-of-service (QoS) considerations. Other QoS attributes include availability, manageability, integrity, and security, which should be balanced with performance and scalability, and this often involves architecture and design tradeoffs.
