Pacing and Pacing vs Think Time


What is the impact when we add pacing in the script? and how is this different from Think Time?


           Adding pacing in the script gives user the control to determine how long it takes for each iteration to complete. Think time is something very basic. All you can do with think time is to let the script think for certain secs before proceeding. But this lacks control. Adding pacing to the script can compensate this problem. In some case, we would like to control the TPM/Volume/Throughput and hence usage of pacing. Think time is fixed. But pacing can be altered and controlled easily. Load runner provides three different options to control/add pacing. They are

  1. As soon as the previous iterations ends
  2. After the previous iterations ends (fixed time)
  3. At a random interval xx to xx secs.
