title: Raspberry PI measure POST request with JMeter
body: <p>I have simple Java EE application for measure by JMeter. Application run on heroku. I write name and surname into textbox on JSP. These are send on server by POST request. Server saves person and return same page with update list of persons. This is functionality which I measure in JMeter. This is result graph:</p>

  <p>I know why Average grows. Because list of person is bigger with each next request. So sending data to client are bigger with each next request and responses are slowly. But why average grows until from approximately half of graph? List yet gain from start testing. I measure on Raspberry PI. On desktop average grows from the start.</p>
