Launch the `jmeter` script in your console from within your jemeter install directory and add a new **Thread Group**.
* Set **Number of Threads** to some high number in your case for example `40`.
* Set **Ramp-Up Period** to a specified interval for example `10` seconds.
* Both **Number of Threads** and **Ramp-Up Period** setup how many request we make in a given period of time. In this example we will use 40 "users" per 10 seconds. In other words we make 4 requests per second.
* Set **Loop Count** to some number for example `10`. It sets how often a test is repeated.
Then add a HTTP Request to simulate a user request. In our example we use one for the REST response in JSON and XML format. Fill in the **Server Name or IP** address, **Port Number** and the **Path** of your request.
Add various **Listerners** to observe the output of the **Testplan**. You can get informed for example about **Response Time**, **Troughput** and **Assertions**.
On the upper right corner you will see a number counting up with a green square lighting up. That means that the testplan is currently running and it will turn gray once the tesplan has finished.
