Why we do performance testing??

Why we do performance testing??

1)For Assessing release readiness

Helps sstakeholders who make decisions about whether an application is ready for release for handling future growth, or whether it requires a performance improvement/hardware upgrade prior to release

2)For Assessing infrastructure adequacy

Determining the capacity of the application’s infrastructure, as well as determining the future resources required to deliver acceptable application performance

Verifying that the application exhibits the desired performance characteristics, within budgeted resource utilization constraints.

3)For Assessing adequacy of developed software performance

Determining the application’s desired performance characteristics before and after changes to the software.

4) For Improving the efficiency of performance tuning

Analyzing the behavior of the application at various load levels.

Identifying bottlenecks in the application.
