Earlier this year, we wrote a couple of articles reviewing the functionality, usability (link to review article) and performance (link to benchmark article) of a bunch of open-source load testing tools. Si nce then, we have uncovered our own open-source load testing tool - k6 - and it would seem it is time for an update to our reviews and benchmarks, so that we both include k6 but a lso test newer versions of the other tools out there.

 

So, here are the NEW AND UPDATED op en source load testing tool benchmarks!

We shared our detailed analysis of open-source load testing tools in a recent review. In that review, we also promised to share the behind-the-scenes benchmarks. In this article, we'll share those benchmarks so you can see how we arrived at our performance review for each open-source load testing tool.
Remember, too, we narrowed the list for this review to what we consider to be the most popular, open-source load testing tools. This list includes:
