kuormitustesteillä

Kuormitustesteillä, known in English as load testing, is a type of performance testing used to determine a system's behavior under a specific, expected load. The primary goal is to identify performance bottlenecks and assess how the system will perform in a production environment. This involves simulating a large number of concurrent users or transactions to observe the system's response times, throughput, and resource utilization.

There are several types of load testing, including endurance testing (testing for a long period to detect memory leaks), spike testing (simulating sudden increases in load), and stress testing (pushing the system beyond its normal operating capacity to identify its breaking point). Load testing is crucial for ensuring that software applications, websites, and other systems can handle expected user traffic without performance degradation or failure.

The process typically involves defining test scenarios, creating test scripts that simulate user actions, setting up a testing environment that mimics production, executing the tests, and analyzing the results. Key metrics observed include response time, transaction per second (TPS), error rates, and CPU/memory usage. Identifying and addressing performance issues identified during load testing before deployment can significantly improve user experience, prevent costly outages, and ensure the reliability of the system.
