Performance Testing and Load Testing Essentials Performance testing and load testing help you understand how a system behaves under pressure. Performance testing measures speed, stability, and resource use. Load testing simulates real user demand to see how the system scales. Together they help you avoid slow pages, failed processes, and unhappy users. Begin with clear goals. Define target response times for key paths (for example, API calls under 300 ms) and an acceptable error rate (less than 1%). Set a rough load level, such as 200 concurrent users, to frame the test plan. ...

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. ...

Performance Testing and Load Testing Strategies Performance testing helps you measure speed, stability, and responsiveness under various conditions. Load testing specifically examines how your system behaves as user volume grows toward expected or peak levels. Together, they reveal bottlenecks, guide capacity planning, and reduce the risk of outages during real traffic. Start with a clear plan. Define service level objectives (SLOs) for response time, error rate, and throughput. Decide which workloads and user journeys matter most to your business. Build a set of test scenarios that reflect typical days, marketing events, and worst-case spikes. Keep tests repeatable so you can track progress over time. ...
