Hi Vijay,

 

There are multiple factors on which your Pacing is dependent. Mainly pacing is used to control number of hits on server.

 

Also, you can calculate pacing using below formula, regardless you need to know no. of users, response time and achieved TPS:

 

No. of users = (Response Time in seconds + Pacing in seconds) * TPS

 

Kindly note that if application response time is having so much deviation and your pacing is fixed then this would impact TPS.

 

You can also use dynamic pacing option as per your requirement.

Hi Thanks for your reply,

 

Here we dont know the response time before execution, and we need to give pacing time before execution right?

 

Before execution we have only No.of users and No.of transactions only.

 

Thanks,

Re: How to calculate pacing time in Load runner?

Hi Vijay,

 

In that case you can use "At Fixed" pacing option.

 

Selecting At fixed/random intervals

This option allows you to start a new iteration at fixed/random intervals for every ‘n’ seconds. If you set 50 seconds, iteration will get started for every 50 seconds.

 

1. Here if total response time of an iteration is 35 seconds then LG will wait for next 15 seconds and then starts next iteration.

 

2. Similarly; if total response time of an iteration is 45 seconds then LG will wait for next 5 seconds and then starts next iteration.

 

In this case you can achieve TPS with given users. Please note that your calculation should be correct.

 

Also, Minimum delay (in seconds) is 0 and the maximum delay is 32000.
