LoadRunner:Staggering Vuser start times
DescriptionThe following method is a quick way to stagger Vuser start times.
Solution
I often use the Controller to start Vusers rather than the scheduler (personal preference, I guess). If you want to stagger your Vusers so they don't all start at the moment you hit "Play," here's a quick and easy method to space them out.
Put this code into the first action they run:
if(atoi(lr_eval_string("{Iteration}")) == 1)
lr_think_time(atoi(lr_eval_string("{Vuser}")) % 10);
Also, add a parameter called Vuser that's the Vuser ID, and a parameter Iteration that's the iteration number.
This basically pauses 1 second * the last digit of their user number; ex. user 101 would wait 1 second before starting, user 106 would wait 6 seconds, etc. It only pauses during the first iteration; after that, there's no pause.
