Apache lebih banyak dikenal sebagai web server. Namun sebenarnya apache juga memiliki tool yang tersedia untuk melakukan benchmark request pada website. Benchmark ini untuk mengetahui jika terjadi banyak request pada website anda, dan bisa kah  server meng-handle-nya load tersebut.

Untuk melakukannya juga sangat sederhana melalui perintah command line, dan bisa dilakukan jika sudah meng-install apache. Namun untuk memastikan package yang diinstall adalah :

sudo apt install apache2-utils

jika sudah terinstall, parameter perintahnya berupa :

ab -n 1000 -c 100 http://website.com/

penjelasan perintah diatas adalah melakukan 1000 request dengan melakukan grouping dalam 1 request 100 kali. Pastikan juga alamat website diakhiri tanda “/”

Jika perintah diatas saya test pada website saya sendiri, ini hasilnya :

ab -n 1000 -c 100 http://alfach.com/
