What is your experience with performance testing of systems?

Experience in performance testing includes planning and executing load and stress tests to evaluate system behavior under different levels of load. I typically used tools such as JMeter or LoadRunner to create scenarios that simulate real users.

During testing, I analyzed metrics such as response time, throughput, resource usage (CPU, memory) to identify bottlenecks and potential points of failure. Based on the test results, I prepared reports with recommendations for optimization.

For example: I ran a load test for a web application with a gradual increase in the number of concurrent users up to 1000 to see how the server handles peak loads.
