Does anyone know how it compares to Gatling (http://gatling.io) ?

I used Locust for a good long time around a year back, and here are some observations.

Locust is awesome to start with, and has master/slave for spawning multiple servers, great for testing real concurrency with large loads. Gatling doesn't have master/slave mode yet.

Main problems with Locust are:

* Lack of good presentation of results (compare Gatling and Locust results, and Locust is very primitive)

* Lack of Pipelines/Scenarios. This IMO was a big deal breaker for me. You can't say: "100% users hit the home screen, out of which 70% add a product, out of which 25% actually pay" etc. This is easily modeled with Gatling, and the same request session with same data falls through each scenario. I'm still following https://github.com/locustio/locust/issues/171 though, but I don't think they have any idea of implementing it.

Gatling is far more advanced but both tools share similar architectural designs regarding how they handle lots of traffic. Locust is more leightweight (and I would say also more easy, but depends on your needs) and is missing good graphical presentations of results and you will not get a browser recorder with it.
