  • 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: 10 months 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 1 year 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 1 year 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 1 year ago

  • Running a Billion Workflows a month with Netflix Conductor
    We used wrk2, a fantastic tool to generate stable load on the server. Wrk2 improves on wrk and adds the ability to generate sustained load at a specific rate (-R parameter). - Source: dev.to / 12 months ago
  • So how does WSGI concurrency work?
    I am using a tool called wrk to make a bunch of requests to my website, and changing the concurrency of the requests drastically changes the result, with concurrency set to 1, I get 894 requests made in 10 seconds, and when I set concurrency to 10, I get 8549 requests. This linear scaling stops when increasing the concurrency more drastically (18805 requests for 100 and 19814 for 500 concurrency). Source: 12 months ago

  • Grasshopper – An Open Source Python Library for Load Testing
    We use locust at work but I HIGHLY recommend wrk for a very robust yet simple load testing tool. https://github.com/wg/wrk. - Source: Hacker News / about 1 year ago
