Load Testing


What's New In Loadero (January 2023)

The first month of 2023 has already ended and we are excited to share the new updates and features that we implemented in Loadero over the past month and some of the fixes we made during that time. If you are using Loadero to test WebRTC solutions, make sure to read the section about updates for WebRTC metrics gathering, it also has information about important upcoming changes.

Frontend vs. backend performance testing

Which should you do: frontend vs. backend performance testing? The short answer is both. Each has its pros and cons, but hybrid load testing combines them and gives you the most holistic view of performance, including frontend concerns like how quickly a page renders or perceived application performance as well as backend concerns like response times of individual components.

How to organize testing scripts in k6 (k6 Office Hours #76)

In this video, we talk about how to organize testing scripts in k6 using features like tags, groups, and functions depending on what type of testing you want to do with your test script. Developer Advocates Paul Balogh, Marie Cruz, and Nicole van der Hoeven show us a few examples of how they would organize and modularize scripts in a test suite.

WebRTC Applications' Performance Monitoring

The last thing a business wants is to be known as an unreliable and poorly performing service, especially if there are similar solutions a few clicks away. So being aware of the performance of a WebRTC application or any other software solution is a must to avoid issues in the future. A solution can be developed by experienced people and tested before it is released, but even so it doesn’t mean performance degradations will never appear.


The reverse load test: it worked for us

As holiday season winds down, we can reflect on the reverse load test that we did to make sure our customers could prepare for their own holiday traffic. What’s a reverse load test? OK, it's a term we just made up. But it started like any load test, with two systems: the load generator and the system under test (SUT). The focus of our test, however, was inverted. In normal load tests, testers really care only about how the SUT performs—that’s the point of the test.


Comparing LoadRunner VS k6

At k6, we get frequent requests to compare k6 vs. LoadRunner, and since I am an experienced user with LoadRunner (even certified), I will try to put both tools head to head. But comparing these tools is difficult as their components do not match 1:1. Each is a robust ecosystem with different parts, some doing multiple things that make straight comparisons more complicated. And on top of that, we constantly get new features that match up with many other components.
