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...

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...

In our blog, we’ve previously had a Tag1 Team Talk about Goose, by Tag1 CEO Jeremy Andrews. Goose is a Locust-inspired load testing tool In Rust. Goose has been effective in helping Tag1 support its clients by ensuring their websites hold up under stress.

Research shows that if your application introduces latency of even a few milliseconds, your business revenue can suffer immensely. At Tag1, we often have clients approach us with concerns about high traffic. Load testing and performance tuning often elicit groans from architects and developers more interested in building features, but it is a critical step in the process to ensuring your web application can operate at scale under heavy load. Though other load testing ecosystems...

Goose is the most scalable load testing tool available (10 - 20x faster than Locust), it uses much less hardware and is the easiest tool to scale. Check out the Goose source code, documentation, and all other Tag1 Goose related content! --- Load testing is one of the tools we leverage regularly at Tag1. It can help prevent website outages, stress test code changes, and identify bottlenecks. The ability...

Locust.io is a great tool for applying load in a controlled manner and measuring response. However, historically speaking nobody has really cared about a solo locust. They just aren't that concerning in the singular. Likewise, load applied from a single point to a moderately complicated infrastructure is both easy to block (or rate limit) and also not very representative of a real world situation. (Aside from the people you inevitably end up talking to who...

Apache JMeter and I have a long and complicated relationship. It is definitely a trusted and valuable tool, but I am also quite confident that certain parts of it will make an appearance in my particular circle of hell. Due to this somewhat uncomfortable partnership, I am always interested in new tools for applying load to an infrastructure and monitoring the results. Locust.io is not exactly a new tool, but I have only recently begun...
