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: 12 months ago
I ran on the same hardware 5k current get requests through https://loader.io/ tool to the server with each db. Source: over 1 year ago

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 2 years ago
