    157 For this example experiment we used the install script facility to automatically install the necessary software and kick-off the experiment. In this very simple setup, we have installed and launched a [http://en.wikipedia.org/wiki/Web_server web server] as well as an [http://en.wikipedia.org/wiki/Iperf iperf server], on the server host. On the client, we have started some processes to test both of these
    158 services. To view the results of this experiment:

     165           After you are done with your experiment, you should always release your resources so that other experimenters can use
     166the resources. In order to cleanup your slice :
     167              <ol type="a">
     168                 <li>Press the '''Delete''' button in the bottom of your canvas </li>
     169                 <li> Select "'''Delete at used managers'''" and '''confirm''' your selection. </li>
     170              </ol>
     171Wait and after a few moments all the resources will have been released and you will have an empty canvas again. Notice that your slice is still there. There is no way to delete a slice, it will be removed automatically after its expiration date, but remember that a slice is just an empty container so it doesn't take up any resources.

    181   * Follow [wiki:HowTo/LoginToNodes these instructions] and log in to the client node
    182   * When you have successfully logged in, run this command

    184 iperf -c server -P 2
    185 }}}
    186     This task shouldn't take more than 30 seconds. Change the number after the ` -P ` argument and watch how the performance is affected while you change the number of parallel TCP connections.
    187   * Scroll all the way down the server iperf log, and look at the logs for your transfers
