UpCloud Web Run Tests

Web Run tests are made of a load test tool and a database intensive Rails web application.

The load test tool sends HTTP requests to the web application at a controlled rate and records HTTP response codes, response latencies and timeouts. The load test tool is multithreaded and runs on the same VPS where the web application runs.

The intent is to measure:

  • the response times (latency) of the web server
  • the amount of CPU used to serve those requests under various load levels
  • what's the maximum load at which 100% requests are served without timing out.

Provider: UpCloud
Plan: 8GB 4 cores
Datacenter: Frankfurt, Germany
Number of CPU cores: 4
CPU type: Intel(R) Xeon(R) CPU E5-2687W v4 @ 3.00GHz

Web Runs by request rate


Note: the P99 is the 99th percentile. The P99 latency is the latency of the 1% slowest HTTP requests in the web run.
