The role of load testing in software performance evaluation is to assess how a system behaves under expected and extreme conditions. It simulates various user loads to determine the application’s response time, stability, and scalability. Identifying performance bottlenecks before deployment is critical for delivering a reliable user experience. Load testing helps ensure that applications can handle peak demands and operate smoothly, preventing potential downtime or slow responses during high-traffic periods. This practice ultimately aids in ensuring high quality and performance efficacy of software products.
