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: about 1 year 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.
