What is Siege?
Siege is a powerful and versatile tool designed for load testing and benchmarking web applications. It allows developers and system administrators to simulate a variety of user interactions with their applications to gauge their performance under different levels of stress. By generating a significant number of concurrent requests, Siege evaluates how well an application can handle traffic spikes, ensuring that it can maintain its responsiveness and stability during high-demand scenarios. With a focus on simplicity and efficiency, Siege provides users with a command-line interface that is both easy to use and highly customizable. Users can specify a multitude of parameters, including the number of concurrent users, the duration of the test, and the specific URLs to target, allowing for precise control over the testing process. The tool also offers detailed reports that summarize the results, including response times, throughput, and error rates, making it an invaluable resource for optimizing application performance. Whether used for stress testing during development or for ongoing performance monitoring in production, Siege is an essential tool for ensuring that web applications deliver a seamless user experience.
