Testing for Performance of a Web Application

Performance testing is testing to determine the responsiveness, throughput, reliability or scalability of a system under a workload.

Why Do Performance Testing?

• To compare the current performance characteristics of the application with the performance characteristics that equate to end-user satisfaction when using the application.
• To verify that the application exhibits the desired performance characteristics, within the budgeted constraints of resource utilization.
• To analyze the behavior of the Web application at various load levels.
• To identify bottlenecks in the Web application.
• To determine the capacity of the application’s infrastructure, and to determine the future resources required to deliver acceptable application performance.
• To compare different system configurations to determine which one works best for both the application and the business.
