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 designing and optimizing the system for optimal performance.

Performance testing is the process of testing the performance characteristics of a system under specific conditions.
Performance engineering is the proactive approach of designing, building, and optimizing a system for optimal performance.
Performance testing measures the speed, responsiveness, and stability of a system.
Performance engineering involves analyzing system architecture, identifying bottlenecks, and implementing optimizations.
Performance testing focuses on evaluating the system's behavior under load and stress conditions.
Performance engineering aims to improve the system's performance by optimizing code, database queries, and infrastructure.
Performance testing uses tools like load generators, monitoring tools, and performance analyzers.
Performance engineering involves capacity planning, scalability analysis, and performance tuning.
Performance testing helps identify performance issues and bottlenecks in a system.
Performance engineering ensures that a system can handle expected user loads and performs efficiently.
Example: Performance testing involves running a website with thousands of concurrent users to measure its response time.
Example: Performance engineering involves analyzing the database schema and optimizing queries for faster data retrieval.

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.
