DEPRECATED: improved version available here

quick_benchmark

A simple C/C++ one header file for quick and dirty benchmarking.

See more examples in the example folder.

Features

• Less than 200 lines of code in 1 header file.
• Customizable benchmark function (default is rdtsc).
• Cross-platform.
• No dependencies (No POSIX libraries. Only standard C libraries).
• Extremely easy and quick to use.

Quick start

Simple benchmark

void my_func(int a, int b, int c)
{
    /* ... */
}

int main()
{
    /* benchmark my_func(10, 23, 50) */
    BENCHMARK(my_func, 10, 23, 50);
}

Group benchmark

void func_version_a(int val, int val2)
{
    /* ... */
}

void func_version_b(int val)
{
    /* ... */
}

void func_version_c(int val)
{
    /* ... */
}

int main()
{
    /* every function gets benchmarked over 2000 iterations for 5 times */
    BENCHMARK_GROUP_BEGIN(stdout, 5, 2000);
        BENCHMARK_GROUP_ADD(func_version_a, 40, 52);
        BENCHMARK_GROUP_ADD(func_version_b, 40);
        BENCHMARK_GROUP_ADD(func_version_c, 40);
        BENCHMARK_GROUP_ADD(func_version_c, 4342);
    BENCHMARK_GROUP_END();
}
