Can you please have a look on below requirements for the load test and suggest us that the configurations we made are suitable to achieve this load test pattern?


Total Test Duration
Ramp-up time
Ramp-down time
Vusers
1 Hour
10 minutes
10 minutes
50 Vu


To achieve above mentioned load test scenario we did below configurations in Stress Stimulus tool under Load Pattern tab:


Load Pattern
Start VU
Step VU increase
Step duration (s)
Max Vu
Increase over time (s)
The
Step Load
1 Vu
1 Vu
12 seconds
50 Vu
0


How do we do the ramp-down?

You will need to set up a custom load that is described http://support.stresstimulus.com/display/doc52/Custom+Load

Create the following ramp up steps:
  • 50 ramp up steps that are 12 seconds each and increment by 1 VU on every step
  • 1 step of 2400 seconds (40 minutes) with 50 VU
  • 50 ramp down steps that are 12 seconds each and decrement by 1 VU on every step

As follows:

Set the Load pattern property to Custom Load and Custom load pattern property to:
1:12;2:12;3:12;4:12;5:12;6:12;7:12;8:12;9:12;10:12;11:12;12:12;13:12;14:12;15:12;16:12;17:12;18:12;
19:12;20:12;21:12;22:12;23:12;24:12;25:12;26:12;27:12;28:12;29:12;30:12;31:12;32:12;33:12;34:12;35
:12;36:12;37:12;38:12;39:12;40:12;41:12;42:12;43:12;44:12;45:12;46:12;47:12;48:12;49:12;50:2400;49
:12;48:12;47:12;46:12;45:12;44:12;43:12;42:12;41:12;40:12;39:12;38:12;37:12;36:12;35:12;34:12;33:12;
32:12;31:12;30:12;29:12;28:12;27:12;26:12;25:12;24:12;23:12;22:12;21:12;20:12;19:12;18:12;17:12;16:
12;15:12;14:12;13:12;12:12;11:12;10:12;9:12;8:12;7:12;6:12;5:12;4:12;3:12;2:12;1:12

The load pattern graph should look as follows:
