Throttling issue with holdfor

I am trying to use throttling but I cannot understand the difference with “holdFor” and “jumpToRps”
This is my simulation:

class TestThrottle  extends Simulation {

  object RESTrequest {

    val initiateRequest = exec(http("Get")

  val httpConf = http
    .baseURL("") // Here is the root for all relative URLs
    .inferHtmlResources(BlackList(""".*\.js""", """.*\.css""", """.*\.gif""", """.*\.jpeg""", """.*\.jpg""", """.*\.ico""", """.*\.woff""", """.*\.(t|o)tf""", """.*\.png""", """.*\.svg"""), WhiteList())
    .acceptHeader("text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8") // Here are the common headers
    .acceptEncodingHeader("gzip, deflate")
    .userAgentHeader("Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:16.0) Gecko/20100101 Firefox/16.0")

  //Now, we can write the scenario as a composition
  val scn = scenario("Scenario Name").exec(RESTrequest.initiateRequest)

  setUp(scn.inject(atOnceUsers(3))).throttle(jumpToRps(10), holdFor(100 seconds)).protocols(httpConf)


I tested 3 times:

  1. setUp(scn.inject(atOnceUsers(3))).throttle(jumpToRps(1), holdFor(10 seconds)).protocols(httpConf). As you can see in the screenshot the duration is 2 seconds and the number of user 2.

  1. setUp(scn.inject(atOnceUsers(3))).throttle(jumpToRps(1), holdFor(100 seconds)).protocols(httpConf). The same here, 2 sec and 2 users

  1. setUp(scn.inject(atOnceUsers(3))).throttle(jumpToRps(10), holdFor(100 seconds)).protocols(httpConf). Here there was 3 request 3 users for 1 second.

I don’t see any difference in the time and the number of request.
