In June 2020, the Dutch government the "coronalijn", a telephone hotline that any resident could call to schedule a COVID-19 test. The system struggled after a whopping 323,000 people called it, a quarter of whom didn't even call for a test. How does fear affect performance outcomes, and what can we do about it as performance engineers?

Load testing video streaming can be technically difficult compared to API load testing because there are metrics other than response time that you need to consider. In this video, Nicole shows how to load test video streaming using JMeter.

In the last video, Nicole discussed how to get started with using test data from a file in Flood Element, but what if you want to make sure that only unique data is used in your load test? You can do this by using a unique variable that identifies every browser instance in your load test and tying the user data to it.

Nicole talks about how to install the JMeter Plugin Manager as well as other plugins, what the best JMeter plugins are, and why you need them. JMeter is an open-source load testing tool that is already robust, but there are some fantastic plugins that have been developed for it that you might want to use in your next load test.

One of our most commonly-asked questions is: "What are the best tools for load testing?" The answer will depend on a few things: your reason for load testing, the application you want to test, what kind of load testing you want to carry out, your team's experience with scripting, and how many virtual users you want to run.
Note from Nicole: In this video, I say that traditional load testing tools can't simulate requests that are triggered by interactions on the client-side. This isn't technically true: if you know what the requests are, you can build those requests manually on a protocol-level tool (like JMeter or Gatling). However, this takes more work compared to browser-level tools that just do this natively.

What is the meaning of concurrent users in performance testing? You might have seen concurrent users in JMeter or other tools, but what does it mean and how can you use the term properly?
