    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

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.

  • express server failing after high number of requests in digital ocean droplet with high configuration

  • 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: about 3 years ago

  • What is the role of QoS for Pods?
    There are tools CastAI (https://cast.ai/) and KubeCost (https://www.kubecost.com/) which helps you get these values. I haven't tried it personally, but they are promising. There are other tools as well. One of the approach OP suggested, monitor the values over a period of time to determine the right requests value, is really good one. I would modify it a bit. Generally take the p95 value for requests and 1.5-2x... Source: about 2 years ago

  • Is k8s Kops preferable than eks?
    Curious about what about cast.ai sets it apart for you? I went with spot because it is owned by a big company and knew it wasn't going to disappear. I think cast was still in invite only mode, as well. Source: almost 3 years ago
  • Scheduled spindown/up of clusters?
    I found that cast.ai seems to have this functionality but am wondering if there is a free option. Also pursuing gMaestro but they're not available on arm64 yet. Source: almost 3 years ago
  • Reducing AWS costs?
    If you're using Kubernetes, CAST AI is the fastest way to significantly reduce your compute bill and keep it there. It manages compute capacity automatically and has dedicated support to get you started even faster. The best part - Kubernetes cost monitoring and security insights are free.
