Install Siege Benchmarking Tool on Ubuntu 20.04

In this tutorial, we will show you how to install Siege Benchmarking Tool on Ubuntu 20.04 LTS. For those of you who didn’t know, Siege is one of the popular HTTP load testings and benchmarking utility tools to measure the performance of web servers under stress. You can perform a stress test using a single URL with a specific number of users or you can put all URLs in files and stress them simultaneously. Siege reports the total number of hits recorded, bytes transferred, response time, concurrency, and return status. Siege supports HTTP/1.0 and 1.1 protocols, the GET and POST directives, cookies, transaction logging, and basic authentication.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Siege open-source regression test and benchmark utility on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.


  • A server running one of the following operating systems: Ubuntu 20.04, 18.04, and any other Debian-based distribution like Linux Mint or elementary OS.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
