loadrunner iterations - newbie question

Hi all,

Is there a way to limit the loadrunner iterations/requests issued by each vuser to those that I want?

Example:
I am using a java code vuser script and set the vusers to run as threads.
I have a 30 minute test with 100 vusers with think times.
I want only 2000 transactions processed in the entire test.

But when I look at the vuser log files, I see 1500 iterations/requests per vuser => 150000 requests in the entire test.

Your valuable input at the earliest is highly appreciated.

Thanks a bunch in advance.

Re: loadrunner iterations - newbie question

Hi all,

Since I did not get any answers yet...let me try to keep it simple and get clarification to my basic questions first --> What does iteration mean in loadrunner?
Is iteration same as the user request issued by loadrunner?

I am kind of stuck at point in my testing. Your help is highly appreciated.

Thanks in advance for your valuable input.

Re: loadrunner iterations - newbie question

You can control the number of iteration by using thinktime and paceing time.


You have 30 mint and you are able to execute 1500 iterations with 1 user (assuming, need data on this). It mean 1 user in 1 mint he is doing 50 iterations(1500/30).

But you need only 1000 in 30 mints, so u need 33 iteration in 1 min(1000/30).

You have extra of 17 iteration.
What is the actual time (for 1500) taken by each iteration ? = 60sec/50 = 1.2 sec

so for 17 iteration , the total seconds are 17 * 1.2 = 20 seconds.

So your think time between each iteration should be 20 seconds.

If you are using more then one users, then u should considered both thinktime and pacing time.

Hope it make you clear.

Regards
Surendra
