A powerful command-line programme called Siege is intended for server and web application benchmarking and stress testing. By simulating concurrent user activity, testers may evaluate a system's capacity to manage heavy traffic and spot performance bottlenecks.

Siege is a robust command-line tool designed for stress testing and benchmarking web applications and servers. It allows testers to simulate concurrent user activity, helping to identify performance bottlenecks and assess how a system handles high levels of traffic.


  1. Siege enables the simulation of multiple concurrent users accessing a web application or server, allowing testers to evaluate its performance under realistic conditions.
  2. It provides the capability to benchmark web servers by measuring response times, transaction rates, and other performance metrics.
  3. Siege supports both HTTP and HTTPS protocols, making it versatile for testing a wide range of web applications and services.
  4. Users can configure various parameters, including the number of concurrent users, the duration of the test, and the URLs to target, providing flexibility in designing stress tests.
  5. Siege allows the introduction of randomized think times between requests, emulating more natural user behavior during a stress test.
  6. It offers multiple output formats, including concise summary reports and detailed logs, making it easy to analyze the results of stress tests.


Installing Siege on Kali Linux is a straightforward process using the package manager. Open a terminal and follow these steps:



Simple Stress Test:


Simulate 10 concurrent users, repeating the test 10 times on the specified URL.

Benchmarking a Website:


Benchmark the specified website, measuring performance over a 1-minute period.

Adjusting Test Parameters:


Test with 50 concurrent users for 2 minutes, introducing a 10-second delay between requests.
