​Key focus areas during (early) Sprint level Performance tests

In Agile development environments, the focus on system performance during early development sprints gets kick started without pushing performance testing to the end (hardening sprint) waiting for the complete system to be ready. There is no standard approach followed to specify the performance...

Is it possible to run high user load test from less number of virtual user licenses?

To know the answer, first let’s understand what is the important of ‘Think time’. Think Times are necessary in Performance Test Scripts to bring in realistic end user simulation. We all know that Think time is the time spend by the end user in thinking and entering the user inputs before...

​Why workload arrival rate does not always linearly increase with User Load

If you know Little’s law, you are already very near the answer. In a closed system (performance test environment), every virtual user fires the next request only after receiving the response for previous sent request. If the system response time increases, time taken fire the next request will...

Simple Tips for Running Right Realistic Performance Tests

Believe me Performance Testing can be 100% waste of time & money if performance tests are not realistic. Always remember that Performance testing tool is a just a enabler to generate multiple user load traffic on the application under test. But if the traffic created by the load testing tool...

How to apply Little's Law to validate performance test results

Performance Testing tools sometimes don’t generate the configured load due to several reasons like low server capacity , erroneous load generation configurations, etc. Hence it is always ideal to validate the performance testing results using Little’s law to ensure performance test results...

Performance Test Environment sizing challenges

Ideally, Performance test environment should be sized with same capacity as that of production to avoid any risk associated in interpreting the system performance characteristics for Production environment. This arrangement helps Performance Tester to primarily focus on the performance &...

Know the difference between Types of Users in Performance Testing

There are several terminologies used to address a system user. Broadly there are 4 types of users : User Base refers to the total number of users who can access the system. For Example: For a online shopping application, the total number of users in different geographies who can access the...
