Thank you KarelHusa for your response.
Its the test requirement from the project. And if you say "virtually it is possible to process 1 M requests with 250 VUs in 30 minutes". How should I configure this. I mean which type of load allocation I should selct (Relative, Equal, Per Scenario) and what be the values inside it.
if you don't have further requirements, you can start with Equal load.
It's good to start with a lower load and gradually increase the number of VUs, e.g. 10, 20, 50, 100, 250 VUs and see how the system responds. Once you know the 250 VUs are feasible, you can start a longer (30 min) test.
Anyway, I recommend to learn the real business scenario and simulate it as close as possible. Successful testing requires enough detailed input (business requirements).
