Performance testing tools (e.g., JMeter, LoadRunner)

Performance testing tools like JMeter and LoadRunner are software applications used to assess how well a website or application handles user activity. They simulate many users accessing the system simultaneously to identify potential bottlenecks or weaknesses. This helps organizations ensure their systems can manage expected traffic, remain responsive, and avoid crashes during peak usage. Essentially, these tools act like virtual users testing the limits of a system under controlled conditions, providing valuable insights to improve reliability and performance before real users encounter issues.
