CppBenchLite

🧪 A lightweight, header-only C++ microbenchmarking library with optional multithreading and automatic iteration calibration.

🔧 Features

• Simple API: cppbench::benchmark(...)
• Optional multithreaded execution
• Auto mode: dynamically determines the optimal number of iterations
• No dependencies — pure C++17
• Easy to integrate into any project

📦 Installation

Just copy include/cppbench.hpp into your project.

No build steps or external libraries needed.

🚀 Example

#include "cppbench.hpp"

void task() {
    // your code to benchmark
}

int main() {
    cppbench::Config cfg;
    cfg.auto_iterations = true;
    cfg.threads = 4;
    cfg.min_total_ms = 300;

    cppbench::benchmark("Auto-parallel benchmark", task, cfg);
}
