How to create a robot to test traffic on my site on localhost?

Question

I have a mysite.com site that is running in a local LEMP environment (Linux, Nginx, Mariadb, PHP7). The site is already ready and I have a database well loaded with many fake data.

Before sending to AWS-EC2, I want to test some accessibility parameters.

So I wanted to know how to create a robot that will simulate several concurrent accesses to my site.

I want to predict which limit of users accessing the system in which it starts to lose the expected income.

Any idea?

How about using the Apachebench?

For example:

$ ab -n 100 -c 5 http://www.google.com/

-n: Specifies the number of HTTP requests.

-c: Indicates amount of simultaneous HTTP connections.

Exit:
