    We use locust to loadtest our C# microservice applications. It has really cool interface and reporting out of the box and you can also execute loadtest from cli / devops pipeline. Only thing is that you need to write loadtests in python. - Source: Reddit / about 2 months ago
  • Load Testing: An Unorthodox Guide
    Agreed with a lot of the points here, like starting small with a single piece of your API, then slowly expanding your tests once you’re comfortable that you know what you’re doing. Note that if you use the Locust framework to write your load tests in Python, it takes care of measuring and reporting the latency and throughput for you. It’s really nice. - Source: Hacker News / 6 months ago
  • CloudRun min max
    For my application, to tune these parameters I used a load testing tool. I built a script using Locust. - Source: Reddit / 7 months ago

  • Load testing workflow for POST API calls
    I used to use JMeter, till someone else on the team introduced me to locust, so check that out if you don’t mind doing some python: There’s also gatling (scala based, but can be generated by a recorder or HAR files), - Source: Reddit / 8 months ago

  • Ask HN: Do you load test your applications? If so, how?
    I’ve used Locust ( which makes it easy to describe usage patterns and then spin up an arbitrary number of “users”. It provides a real-time web dashboard of the current state including counts of successful & failed requests. - Source: Hacker News / 9 months ago
  • So I've installed grafana, loki, and prometheus on the personal Kubernetes cluster via Terraform. Now what?
    Thanks! I currently run Pritunl on the cluster, but I could definitely host my resume on there as well. I could stand to learn tools like or Bees With Machines Guns as a load testing exercise for sure. I will dive into it! - Source: Reddit / 9 months ago
  • How does one benchmark performance for async functions?
    Personally, I prefer to rely on external testing — typically with Locust — for my benchmark numbers, and use instrumented metrics for other purposes. - Source: Reddit / 10 months ago
  • Is there a way to test the scalability of a web server (or any type of server)?
    There are a bunch of load testing tools available that let you throw a bunch of requests at a server and see how it copes, my personal preference is - Source: Reddit / 11 months ago

  • I’ve learn django and have built projects but what do i need to learn after in order to handle millions of users on my app?
    Millions? Well... If you have hundreds, you can checkout django-silk and Locust, to improve performance. Other buzzwords are Kubernetes, Docker, Docker Swarm, Load Balancing. For Millions of User, you'll need a team. - Source: Reddit / 12 months ago

    Sounds like a good use case for load testing. Since it seems like you’re already comfortable with Python, you should be able to load test easily with Locust. - Source: Reddit / about 1 year ago
  • App for testing Django end-to-end
    I was wondering if there are any de-facto standards for testing the setup configuration and performance. For example, I was wondering if there is a stress-test Django app (application-agnostic) which populates the DB with some test data, sets-up a few demo endpoints (e.g. One that does computation-intensive operations, one that does DB-intentesive operations, one that simply sleeps, etc.) that can be used in... - Source: Reddit / about 1 year ago
  • How would you do load testing in this scenario?
    As for the backend/api testing, there are plenty of tools out there - I'd recommend using, which is super easy to get started. - Source: Reddit / about 1 year ago
