Apachebench, benchmarker un serveur rapidement

Vous voulez benchmarquer un serveur de manière rapide et simple? Bon ok, c’est pas du vrai test en charge comme ce que l’on pourrait faire avec JMetter, mais ça permet d’avoir une idée des perfs et de pouvoir comparer des évolutions.

sudo apt install apache2-utils

Puis :

ab -n 30000 -c 30 http://localhost:8080/
-n : le nombre de requêtes
-c : le nombre de requêtes en parallèle
Et hop un résultat :
