  • 15 Common Kubernetes Pitfalls & Challenges
    Regularly review your cluster's utilization to check whether it's still suitable for your workloads. Test autoscaling rules by using a load-testing tool like Locust to direct excess traffic to your cluster. This lets you spot problems earlier, ensuring your Pods will scale seamlessly when real traffic arrives. - Source: dev.to / 9 months ago
  • Small-Scale Chaos Testing: The Missing Step Before Production
    Locust: While primarily a load testing tool, it can be used to simulate user behavior under stress. - Source: dev.to / 10 months ago
  • Log Spikes? Noย Sweat: How Top DevOps Teams Tame Bursty Workloads
    But you donโ€™t have to operate at Netflixโ€™s scale to benefit from the same mindset. Effective teams simulate log floods during load tests, which push traffic through staging environments while tracking how ingestion, indexing, and alerting respond to the increased load. Tools like Grafanaโ€™s k6 and Locust can simulate thousands of requests per second, while synthetic log generators mimic bursty error scenarios. - Source: dev.to / about 1 year ago
  • Serving 200M requests per day with a CGI-bin
    I mean honestly - the "classic" Apache model of throwing things into the www root is very strong for rapid development. Hot code reloading is sometimes finicky, you can end up with unexpected hidden state and lose sanity over a stupid heisenbug. Trust me. IMO you don't need to compensate for bad configs if you're using a proper staging environment and push-button deployments (which is good practice regardless of... - Source: Hacker News / about 1 year ago
  • 3 Types of Chaos Experiments and How To Run Them
    Use load testing tools like JMeter, Gatling, or Locust to simulate demand spikes and verify that your auto-scaling rules work as expected. This will ensure that your system can handle real-world traffic patterns. - Source: dev.to / about 1 year ago
  • Outgrowing Postgres: How to identify scale problems
    Use load testing tools like Apache JMeter, Gatling, or Locust to measure your application's throughput under various loads and compare it to historical data. - Source: dev.to / over 1 year ago
  • Five Advanced Techniques to Improve Automated Testing by 50%
    You should also incorporate performance testing into your daily builds to catch performance regressions early. For this, you can use Locust for load testing. You can also implement performance budgets in your CI/CD pipeline. This will allow you to fail builds that don't meet performance criteria, ensuring performance doesn't degrade over time. - Source: dev.to / over 1 year ago
  • Why your FastAPI (or Flask) App performs poorly with high loads
    These tests were done on GCP Cloud Run using a single processor, and 512M RAM machine, and we used Locust, an incredible tool (for Python, LoL). - Source: dev.to / over 1 year ago
  • How MySQL Tuning Can Dramatically Improve WordPress Performance
    Our test duration was 2 days. To handle this longer testing period, we switched from BlazeMeter (max test duration of 20 minutes) to Locust, an open-source load-testing tool. - Source: dev.to / about 2 years ago
  • Load Testing with Locust
    This week at work I was tasked with continuing some load testing that a previous Engineer had started. They had used locust which is an open source load testing tool to run the initial load testing on the staging environment. I now needed to do the same for production so I followed in their footsteps. - Source: dev.to / about 2 years ago
  • Why Quarkus Native (probably) does not fit your project
    Finally, let's compare the response time of the requests. For that, we will use Locust , an open source load testing tool. The tests will run for 5 minutes, and will increase 4 requests per second every second until they reach 1000 requests per second. - Source: dev.to / over 2 years ago
  • What is Load Testing? Complete Tutorial With Best Practices
    Locust: Another open-source tool, Locust is particularly flexible due to its support for Python scripts. It can conduct load tests across multiple machines, making it possible to simulate millions of users simultaneously. An exceptional feature of Locust is its web-based UI, which allows real-time tracking of performance metrics during test execution. - Source: dev.to / over 2 years ago
  • API Load Testing: Enhance Your Skills with Locust
    Locust is a perfect tool to use on such occasion:. - Source: dev.to / over 2 years ago
  • Breaking the 300 barrier
    So, in theory, we can handle 300 requests per minute on a single server which was the assumption we started with. After this, I decided to play with this configuration and see what we could achieve. But, to go ahead I need a system to measure the metrics of our load testing. So I quickly set up Locust on my system. Locust is an open-source easy to setup load-testing framework. - Source: dev.to / over 2 years ago
  • The Power of Traces: Learn by Contributing to OpenTelemetry
    The OpenTelemetry Demo is composed of microservices written in different programming languages that talk to each other over gRPC and HTTP; and a load generator which uses Locust to fake user traffic. - Source: dev.to / over 2 years ago
  • The Uncreative Software Engineer's Compendium to Testing
    Locust: is an open-source load testing framework that allows you to define scenarios using Python code. It simulates a large number of concurrent users and measures the performance of your web applications and APIs. - Source: dev.to / almost 3 years ago
  • Performance UI Testing
    Like many suggested, I would tackle this by putting load via apis(https://locust.io) while running a selenium UI test at the same time in a loop to collect eventLoadTime until the api has finished running completely. You can then aggregate the load time and present your report. I donโ€™t think thereโ€™s any other viable way to load test UI. Good luck ๐Ÿ‘. Source: about 3 years ago
  • Free Tech Tools and Resources - Mac Scrolling, Load Testing, Win Server Switch Tip & More
    A Free Tool UnnaturalScrollWheels is a MacOS app that allows you to invert the scroll direction for physical scroll wheels while maintaining the normal function for trackpads. Aew3 recommends it "for those like me who go between dock and laptop and prefer my mouse to have a different scroll direction to the trackpad." Another Free Tool Locust is an open-source load testing tool that allows you to define... Source: about 3 years ago
  • Stress testing new network, what tools to use? Preferably free
    If you want to test an actual application and how it handles network latency, potential buffering, QoS etc, then you could use Locust to stress-test REST-based applications and their APIs. Source: about 3 years ago
  • Web server for production with flask
    How do you handle state? Use something like locust to exercise the client with some actual load - you will be surprised how many bugs come out under these tests. Source: about 3 years ago
  • How much async is too much async?
    Load test suite (usually Locust because it's written in and scriptable with Python). Source: over 3 years ago
