C++ Crow vs. Rust Axum: Raw HTTP Parsing Performance and Peak Resource Consumption

Benchmarking Methodology: HTTP Request Parsing

To rigorously compare the raw HTTP request parsing performance and peak resource consumption of C++ Crow and Rust Axum, a standardized benchmarking suite was developed. The objective is to isolate the overhead introduced by the web frameworks themselves, minimizing external dependencies and network latency. We’ll focus on parsing incoming HTTP requests, specifically the headers and body, under high concurrency. This scenario is representative of API gateways, reverse proxies, and high-throughput microservices where efficient request handling is paramount.

The benchmark simulates a constant stream of POST requests with a moderately sized JSON payload (approximately 1KB). The server’s task is to receive the request, parse its headers, extract the body, and perform a minimal validation (e.g., checking for a specific key in the JSON). No complex business logic or database interaction is involved to ensure we are measuring the framework’s intrinsic parsing and request handling capabilities.

C++ Crow Implementation

The C++ Crow framework, known for its minimalist design and performance, was chosen for its direct approach to HTTP handling. The implementation focuses on leveraging Crow’s built-in request parsing capabilities. We’ll use a simple POST endpoint that accepts JSON and returns a 200 OK response after basic validation.

Crow Server Code

The following C++ code demonstrates a basic Crow application. It sets up a single endpoint that expects a JSON payload. The `request.body` is accessed directly, and `Crow::json::load` is used for parsing. Error handling for invalid JSON is included.

#include <crow.h>
#include <iostream>
#include <string>
#include <vector>

int main()
{
    crow::SimpleApp app;

    // Define the endpoint for POST requests
    CROW_ROUTE(app, "/parse_json")
    .methods(crow::HTTPMethod::POST)
    ([](const crow::request& req) {
        std::string body_str = req.body;
        crow::json::rvalue json_body;

        try {
            json_body = crow::json::load(body_str);
        } catch (const std::exception& e) {
            return crow::response(400, "Invalid JSON: " + std::string(e.what()));
        }

        // Minimal validation: check for a specific key
        if (!json_body.has("message")) {
            return crow::response(400, "Missing 'message' key in JSON");
        }

        // Return a success response
        return crow::response(200, "JSON parsed successfully");
    });

    // Set the logging level to suppress verbose output during benchmark
    app.loglevel(crow::LogLevel::CRITICAL);

    // Run the application on port 8080
    app.port(8080).multithreaded().run();

    return 0;
}

Compilation and Execution

To compile this code, you’ll need the Crow library and a C++17 compliant compiler. A typical compilation command using g++ would be:

g++ -std=c++17 -pthread -o crow_server crow_server.cpp -lboost_system -lboost_thread -lboost_filesystem -lboost_regex -lboost_date_time -lboost_atomic -lboost_chrono -lboost_context -lboost_coroutine
