    There may be limitations on the geographical distribution of clients, which could affect tests intended to simulate traffic from varied regions.

  • 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: over 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: almost 3 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: almost 3 years ago

  • Ask HN: How did your startup get the first payment?
    I would say almost from day 1. Even at a lower price, it's an important step to validate an idea. When people need to put their credit card in and give you money, it's another level of commitment that I don't think you will have with a free plan. It is a level of commitment from the user but also from you. If you're getting paid, it's expected that, for example, if a service is down/not working, you need to fix... - Source: Hacker News / almost 3 years ago
