Hi, Description of Ramp Up period in the user manual : This property tells JMeter how long to delay between starting each user. For example, if you enter a Ramp-Up Period of 5 seconds, JMeter will finish starting all of your users by the end of the 5 seconds. So, if we have 5 users and a 5 second Ramp-Up Period, then the delay between starting users would be 1 second (5 users / 5 seconds = 1 user per second). If you set the value to 0, JMeter will immediately start all users.
Usecase description: I have 5 users in the thread, a Ramp Up period set to 5 sec and the duration set to 300 sec in the Scheduler configuration. So for the first 5 seconds each thread is invoked with a delay of 1 sec, but is the same behavior(next thread is delayed for 1 sec) exhibited for the next 300 secs of test duration? And also i was not clear as to how Ramp Up period is advantageous? and when to (and when not to) set this Ramp Up period? Thanks, Prasanna
