Performance Testing for Scalable Systems
Performance Testing for Scalable Systems As systems grow, performance testing helps teams verify that an app can handle more users without failing. It measures speed, reliability, and how resources are used. When a service scales, bottlenecks can hide under normal load and appear only under peak traffic. A simple load test is useful, but a complete plan covers patterns you expect in real life and some worst cases. Why test for scalability Testing for scalability means setting clear goals. Decide acceptable latency, error rate, and resource limits. Then design tests that mirror how people use the product—browsing sessions, search, checkout, or API calls. This helps you see not just fast responses, but how the system behaves when many tasks run at once. ...
