How to add pacing dynamically in a HP LoadRunner script

I am working on a performance testing project using HP load runner, my requirement is to add pacing dynamically through script for each and every iteration. I did lost of research, but couldn't find one solution for this. Can someone please help in this?

If you want actual script pacing and # of seconds is accurate enough you could use something like this -

int i, iPacing;

iPacing = 5; // Number of seconds to wait between passes of the script

lr_save_datetime("%H%M%S",DATE_NOW,"dCurTime");

i = atoi(lr_eval_string("{dCurTime}")) - atoi(lr_eval_string("{dStartTime}"));       

if (i >= iPacing){
   Action1();
   Action2();
   Action3();   
   lr_save_datetime("%H%M%S",DATE_NOW,"dStartTime");
}

That very last line also goes in the vuser.init to set the initial start time.

If you want direct controlled pacing which will not be affected by your thinktime settings then you can use sleep(milliseconds); for a delay. You should also be able to pull the iteration number using a parameter.

I have used this type of model for a decayed pacing model with a sleep() at the end of the iteration with a fixed value divided by iteration number.

Use the following code at the beginning or at the end of your action block:

lr_thinktime(atoi(lr_eval_string("{paramname}")));

paramname is the name of a parameter which will be a random number type. you can easily create a parameter with the help of parameter file settings.

There is an LR function in load runner LR_thinktime(), it takes second as parameter input. Example: LR_thinktime(5), will make your script think for 5 seconds. You can use this function to induce required pacing in you vugen script. Have some logic to calculate pacing in seconds and pass it to LR_thinktime(). Hope this helps you!!
