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:
| Provider: | Evolution Host Ltd |
| Plan: | Professional |
| Datacenter: | Montreal, Canada |
| Number of CPU cores: | 8 |
| CPU type: | AMD Ryzen 7 3800X 8-Core Processor |
Note: the P99 is the 99th percentile. The P99 latency is the latency of the 1% slowest HTTP requests in the web run.
| Rate (reqs/s) | Average Latency | P99 Latency | CPU idle | CPU steal | Successful requests | Timed out requests | Duration (minutes) |
