How to test RESTful web service performance

Question

I have a RESTful web service (tornado), including login page, fetch data api, post data api and so on. To fetch or post data, the user need to login in advance. Now I want to test the performance of my service.

I just google it, and find that I can use Apache Bench to test. something like：

> ab -n 100 -c 10 http://example.com

Now I can check the performance of login page, but how to login and test "fetch data api" through Apache Bench

Answer 1

It depends on how your app authenticates users.

If it uses cookies, then the simplest way I can think of is to login to the website in any modern browser, open the browser's Dev Tools and look for the cookie that came back from the server.

Pass that cookie to Apache Benchmark using the -C option and have the url as the secure page that you want to test.
