65. You are running a test and notice that during the ramp-up, the response times are beginning to drastically increase. How can you instruct LoadRunner to stop ramping-up Vusers and hold the current number? Press the STOP button on the Controller’s main window Press the PAUSE button on the Interactive Schedule Graph Select the option to wait for the current iteration to end before stopping Select the Vusers in the Ready state from the Vusers window and click the STOP button 66.

The login business process is in the vuser_init section and the Vusers are defined to initialize all Vusers before running. The login business process is in the vuser_init section and the Vusers are defined to initialize 1 Vuser every 10 seconds. The login business process is in the action section and the Vusers are defined to initialize all Vusers before running. The login business process is in the action section and the Vusers are defined to initialize 1 Vuser every 10 seconds. 69.
