Experimenting with running Goose load tests from AWS, Goose has proven to make fantastic use of all available system resources, so that it is only generally limited by network speeds. A smaller server instance was able to simulate 2,000 users generating over 6,500 requests per second and saturating a 2.6 Gbps uplink.

Load testing is a critical part of the quality assurance process in any business website. Knowing how your website behaves under load, and being sure it will stay up can make the difference between success and failure for your business. Retail websites require this for major events such as Black Friday and Cyber Monday. News outlets need to be sure that their readers can reach them and they can respond during major news cycles.

Goose, the highly scalable load testing tool created by Tag1 Consulting, has undergone a number of improvements since its creation. Asynchronous support created a significant boost in performance, but Jeremy felt there was still room for improvement.

In previous posts we’ve talked about Goose, and Gaggles, and how they work. Running Goose for an actual client load test is the true test of its use and, like any software, one of the best ways to find out where additional improvements can be made. Here, we’ll walk through how we set up and proceeded through a test with a Tag1 client, what we found, and where, and what Goose improvements are being added...

Introduced in Goose 0.7, Async enables the simulation of considerably more "users" by giving up the CPU when a task is blocked. For example, when a Goose "user" requests a web page, it's blocked until the server responds. Without Async, Goose blocks an entire CPU core while waiting for that response. With Async, Goose makes the request, then gives up the core (ie, sleeps) allowing another "user" to make a request with that same core...

We’re going to dig into the process of a working Gaggle, so you can see how it runs, and how to deal with some of the errors you might encounter as you start working with this feature of Goose. Goose does not currently have a UI; this example expects you to be familiar with the command line interface (CLI). This example uses one Manager and two Workers, so there are three different things going...

Goose, the load testing software created by Tag1 CEO Jeremy Andrews has had a number of improvements since its creation. One of the most significant improvements is the addition of Gaggles. A Gaggle is a distributed load test, made up of one Manager process and one or more Worker processes. The comparable concept in Locust is a Swarm, and it's critical for Locust as Python can only make use of a single core: you have...
