What is the importance of performance testing in software development?

Performance testing is crucial as it ensures that applications can handle expected loads, providing a smooth user experience.

What are the key metrics to consider during performance testing?

Key metrics include response time, throughput, resource utilization, and error rates, which help assess application performance.

How often should performance testing be conducted?

Performance testing should be conducted regularly, especially before major releases, after significant changes, or during peak usage periods.

What tools are commonly used for performance testing?

Common tools include JMeter, LoadRunner, and Gatling, each offering unique features for simulating user loads.

Can performance testing help in reducing costs?

Yes, by identifying bottlenecks early, performance testing can prevent costly downtime and improve resource efficiency.
