Apache benchmark with Siege

Siege is an http load testing and benchmarking utility. It was designed to let web developers measure their code under duress, to see how it will stand up to load on the internet. Siege supports basic authentication, cookies, HTTP and HTTPS protocols. It lets its user hit a web server with a configurable number of simulated web browsers. Those browsers place the server "under siege."

Siege can be installed with yum (2.66 version from rpmforge repo or 2.70 version from epel repo) or from sources that can be found on the project website. In our case, we will use rpm package from epel repo.

Installation and initial configuration :

[root@localhost ~]# yum install siege -y
[root@localhost ~]# siege.config
New configuration template added to /root/.siegerc
Run siege -C to view the current settings in that file
[root@localhost ~]# siege -C
CURRENT  SIEGE  CONFIGURATION

WebWait - Benchmark your Website

WebWait est un site permettant de tester votre connexion web ainsi que les performances de votre site. En effet, on va mesurer le temps d'accès au site.


Il suffit d'entrer l'URL du site web et de cliquer sur le bouton "Time it !". On peut préciser le nombre d'appels et l'intervalle entre ces appels pour le bench.
Sur la partie droite, on peut voir un aperçu du site testé.


A la fin du test, le résultat affiché correspond à la moyenne du temps d'accès sur la totalité des appels.
Ceci permettra d'avoir une idée sur les performances du site testé et de constater la fluidité de la navigation coté utilisateur.
