Gatling
Gatling is a highly capable load testing tool. It is designed for ease of use, maintainability and high performance. Out of the box, Gatling comes with excellent support of the HTTP protocol that makes it a tool of choice for load testing any HTTP server. As the core engine is actually protocol agnostic, it is perfectly possible to implement support for other protocols. For example, Gatling currently also ships JMS support.
AWS Device Farm
Run tests across a large selection of physical devices in parallel from various manufacturers with varying hardware, OS versions and form factors.
Apache JMeter
It is open source software, a 100% pure Java application designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions.

Review ofLocustLocust

This is the best open source tool i have ever come across which does load testing at its best.

Python config code is really simple to write and good part is its extendable and there are many hooks available ... what else you need ..

Lastly, the web UI to monitor your swarming activity is too good and very helpful for identify bottlenecks and spikes real-time.

I don’t remember exactly how I heard about Loader.io. I think I was adding load testing services to Leanstack. I saw it was a SendGrid Labs project, so there would be competent people behind it. And since they had a Heroku Add-On it was easy to get started. Loader.io is cool because it’s super simple to set up.

We have about 30 tests set up for different pages: loader.io setup

When executing tests, you can see error rate and average response times. But we also check the Heroku logs to see if they are real errors.

My biggest complaint: figuring out what load to set for your tests is difficult. We don’t understand the language they use and no one we’ve spoken to that has used Loader.io understands it either. We’ve been testing at 250 clients (maintain client load) for all of our tests on 2 dynos. That means a constant load of 250 people using the site over a minute, or so I thought. The number of requests at the end of the test suggests it’s more like 250 additional clients hitting the site every second for a minute. But I guess accommodating a higher load is better anyways? 250 concurrent users seems to be our average HN traffic spike so that’s why we went with that load.

I use loader.io for distributed load testing.

That especially matters when you have a cross-region load-balancer and you want to make sure how your app behaves on a global scale.
