Why Does software Performance Testing Required?
Most common reasons for conducting performance testing can be summarized as follows:
To compare the current performance characteristics of the application with the performance characteristics that tally to end-user satisfaction when using the application.
To test that the application exhibits the desired performance characteristics, within the budgeted constraints of resource utilization. These performance characteristics may include several different parameters such as the time it takes to finish a particular usage scenario (called as response time) or the number of simultaneous requests that can be supported for a particular operation at a given response time. The resource characteristics may be set with respect to server resources such as processor utilization, memory, disk input/output (I/O), and network input/output.
To analyze the behavior of the Web application at various load levels. The behavior is measured in measurement/Metrics related to performance characteristics, as well as other metrics that help to identify bottlenecks in the application.
To identify bottlenecks in the Web application. Bottlenecks can be caused by several issues such as memory leaks, slow response times, or sometimes contention under load.
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.
There are risks associated with lack or improper performance testing. Some considerations are outline below:
1. Revenue losses to the competition due to scalability, stability issues.
2. Loss of credibility that may affect the branding image of the company.
