Open? Or Closed? On Workload Models for Performance Testing

There are many differentiating properties when it comes to load and performance testing tools. The general workload model is one aspect that is often overlooked. However, tests that run using the wrong workload model can vastly underestimate latencies and provide a false sense of security. In the following we explain what workload models are and we shed some light on why we believe that StormForger is using the “right” approach for many, if not most cases.

Cookie Domain Mapping

Cookie Performance testing often happens on non-production systems, like a QA or dedicated "perf" environments. In some cases it is easier to directly access those systems for testing instead through a load balancer serving traffic under a shared domain. This approach leads to a typical problem though: Cookie domain mismatches and lost sessions.

Load Testing Engine Evolution

Load testing engine evolution StormForger's load testing engine has been based on Tsung since we started our SaaS offering in 2014.

Load testing engine evolution There is one source of performance problems we've been encountering even before we started with StormForger and still see every time: Missing HTTP Keep-Alive. This article is about why this is still a problem and relevant in 2020 and why performance testing is an important tool to uncover such issues.

Performance Testing at over 1 Million Requests per Second

Load testing engine evolution At StormForger we regularly evaluate our load testing setup and infrastructure to make sure everything works as expected for our customers and to anticipate issues early on. Since we have been working on a revamp of our core load testing engine for the past weeks and months it was about time to scale our internal testing efforts up to eleven!
