It sustained ~27,000 RPS locally with p99 < 30 ms (using a Ryzen 5 5600G). Keep in mind, that this was a local benchmark that does not reflect real networks and it does not utilize TLS, auth, databases, or disk usage. Check out `benchmarks/benchmark-results.txt` to see the benchmark results captured with k6. + +### Test Setup + +Load generator: k6 (local execution) +Scenario: `constant_request_rate` +Target rate: 30,000 requests/second +Duration: 10 seconds +Max VUs: 20,000 (only reached a maximum of 945 VUs) + +Client machine: +AMD Ryzen 5 5600G (local Linux system) + +The load generator and server were executed locally. As a result, the benchmark reflects the combined limits of the server and the client machine. + +### Interpretation + +- The server maintained low and stable latency even at very high request rates. +- No errors or timeouts occurred, indicating the server was not saturated. +- The test experienced dropped iterations, which suggests the benchmark was limited by the local load generator and PC hardware, not the server itself. + +As such, these results demonstrate that the server can reliably handle at least ~27k requests per second on the tested hardware. + +## Benchmark Comparison (cpp_http_server versus Express server) + +I made sure that the node express server implemented multi-threading to provide a more fair comparison with the cpp_http_server. +Check out `benchmarks/node_server` to see the node express server implementation. + +The cpp_http_server is ~1.562x faster in throughput or about 56.2% higher request rate. + +Calculation: 27,366.734925 RPS /
