Given a scenario where an API is experiencing slower response times during peak traffic hours, what would be your primary focus in performance testing?

In scenarios of peak traffic, Load Testing is crucial to understand how the system performs under normal and expected peak loads. It helps identify bottlenecks and performance issues during high user activity. Stress Testing is designed to evaluate system behavior under extreme conditions, but it might not pinpoint issues specific to peak traffic. Spike Testing focuses on sudden spikes in traffic, while Endurance Testing assesses system stability over prolonged periods.
