I want to know how to calculate number of users, Think time, Pacing time and number of Iteration for load testing.

Requirement is:

  1. I need to achieve 10000 transaction per hour.

  2. Need to do 1 hour execution.

  3. My script contains 7 transactions.

  4. Overall Response time is 16 sec without think time.

Depending on your load testing tool the functionality to execute 10000 transactions per hour can already be there, for example in Apache JMeter there is Constant Throughput Timer

If it's not there - the calculation would be something like:

  1. I user executes 7 transactions in 16 seconds
  2. It means that in 1 hour a user will execute 225 transactions, so you need to put 225 iterations in your load config.
  3. Given you want to execute 10000 requests - you will need 10000/225 = 44.4 users for this.

If you're going to use more than 44.4 users - you will need to adjust pacing accordingly using i.e. this Pacing Calculator or this formula
