How do you create Workload modelling in Performance Testing

Workload modeling identifies one or more workload profiles to be simulated against the tested application. The workload model then attempts to approximate real life usage scenario and includes different user types and characteristics.

Hi Vasanth! Thx for this video! It is a really well presented approach of workload modelling for Performance Testing! Let me ask 2 questions:
1. I'm curious, how you replicate real production load on a test server before introducing changes in infrastructure or code?
2. What are the implications when changes are tested directly in production without simulating real load on a test server first? Do you have any specific examples when such a situation negatively impacted your application's performance or the user experience?
Looking forward to hearing your experiences - the good, bad, and ugly 🙂 Thanks in advance for sharing!

1. To answer your first question, I scale down the production to test based on all its configuration, the number of app/web/db servers, their ram, cpu. Once all these are calculated, I will execute load test based on the analytics collected from production and they will be scaled down and will execute multiple load tests. Once the load tests are completed, I will then execute stress test to check the maximum user load the system load can handle and will scale up to match the production load.
2. To answer your 2nd question, I have tested directly in production before the application has been launched. This is to test the maximum user the system can handle. Always the performance tests are executed to unearth the bottlenecks. So no harm in executing in any environments that we get. Its all about finding the bottlenecks.

Thank you so much

@@littleslawyoutubechannel Is it a problem for you to test performance in the testing environment under production load conditions? And how important it is (from 0 to 10)?

Hi Vasanth, Its pretty informative video for Performance tester/engineers to understand the importance of Workload modeling.
Can you please do one video on pacing and its importance, how to measure it and implementing on performance testing achievement.

[@littleslawyoutubechannel]

Yes sure @sandeep

Hi sir , thank you for the video correct me if I m wrong 2nd sheet / example u mentioned for workload modelling can be used for API performance testing

[@littleslawyoutubechannel]

Yes you are right
