locust features and specs

  • Scalability
    Locust is designed to distribute the load tests across multiple machines, allowing for high scalability and the ability to simulate millions of users.
  • Python-based
    The tool is written in Python, which makes it highly flexible and suitable for those who are familiar with the language. You can write custom test scenarios easily.
  • Web-based UI
    Locust provides a user-friendly web-based interface that makes it easy to monitor and control the test execution in real-time.
  • Real-time monitoring
    During test execution, you get real-time statistics and charts that help in monitoring the performance and load.
  • Open-source
    Being an open-source tool, Locust allows for community contributions and is free to use, which helps in continuous improvement and support from the user base.

Possible disadvantages of locust

  • Setup Complexity
    Initial setup can be somewhat complex, especially for large scale or distributed tests. Requires experience with Python and potentially other infrastructure setups.
  • Resource Intensive
    Locust can be resource-intensive, requiring significant compute resources, particularly when simulating large numbers of users.
  • Steeper Learning Curve
    Despite its flexibility, the requirement to write test scenarios in Python may present a learning curve for users not familiar with programming.
  • Limited Protocol Support
    Primarily designed for HTTP/HTTPS protocols, Locust might not be suitable for load testing applications that use other protocols without additional customization.
  • Dependence on External Libraries
    While the use of Python offers flexibility, it also means that you might need to rely on external libraries and tools, which can introduce dependency management issues.

Loader.io features and specs

  • Ease of Use
    Loader.io offers a straightforward and intuitive user interface, making it easy for users to set up and run load tests without a steep learning curve.
  • Quick Test Setup
    With Loader.io, you can quickly set up load tests by simply verifying your website, inputting the target URL, and defining parameters such as duration and the number of clients.
  • Scalability
    Loader.io allows you to scale your tests from a few clients to hundreds of thousands, accommodating different testing needs.
  • Free Tier
    Loader.io offers a free tier that allows users to perform basic load testing, which is great for small projects or initial testing phases.
  • Integration
    Loader.io integrates well with other services and CI/CD pipelines, enabling automated performance testing as part of your development workflow.

Possible disadvantages of Loader.io

  • Limited Test Duration
    The free tier and some lower-tier plans have limitations on the duration of load tests, which might not be sufficient for testing long-running processes.
  • Complex Scenarios
    Loader.io may not support highly complex testing scenarios out-of-the-box, such as tests requiring advanced scripting or multi-step transactions.
  • Resource Limitations
    High concurrency and load levels may require higher-tier plans, which can become costly for larger-scale testing.
  • Geographic Limitations
    There may be limitations on the geographical distribution of clients, which could affect tests intended to simulate traffic from varied regions.
  • Reporting
    While Loader.io provides basic reporting, it may lack the depth and customization options offered by some other performance testing tools, such as detailed analytics and advanced visualization features.

  • 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 / 11 days 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 / 3 months 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 / 4 months 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 / 7 months 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 / 10 months ago

  • express server failing after high number of requests in digital ocean droplet with high configuration
    I wanted to see how many requests can this server handle, so I have used loader.io and run10k requests for 15 seconds. But it seems 20% percent of request fail due to timeout, and the response time keep increasing. Source: almost 2 years ago
  • Why everyone says PostgreSQL better then mongo?
    I ran on the same hardware 5k current get requests through https://loader.io/ tool to the server with each db. Source: about 2 years ago

    Loader.io — Free load testing tools with limitations. - Source: dev.to / over 2 years ago
  • How to stress test my website?
    We put 50 servers of puppets against 50 http servers and see who wins. Ever had 10,000 in your checkout line at once? loader.io is for posers. Also what if there's 250,000 wanting to join the checkout line. Well we can scale to the moon and not handle that. I recommend a waiting room like Queue It. Source: over 2 years ago
  • Best Way to Benchmark Web Hosting?
    I've used what you said, identical setups (with Wordpress) and some plugins: WordPress Hosting Benchmark tool and WP Performance Tester plus some runs with loader.io. Source: over 2 years ago
