What is the difference between performance testing and performance engineering?

Question

Accepted Answer

Performance testing focuses on evaluating the speed, responsiveness, and stability of a system, while performance engineering involves optimizing the system for better performance.

Performance testing is a subset of performance engineering.
Performance testing measures the system's performance under specific conditions.
Performance engineering includes analyzing, designing, and implementing improvements to enhance performance.
Performance testing identifies bottlenecks and issues, while performance engineering addresses them.
Example: Running load tests to measure response time is performance testing, while optimizing code or infrastructure for better response time is performance engineering.

Accepted Answer

In performance testing, testing cycle includes requirement gathering, scripting, execution l, result sharing and report generation. 
            Performance engineering is a step ahead of performance testing where after execution, results are analysed with the aim to find the performance bottlenecks and the solution is provided resolve the identified issue.
