Benchmarks

Benchmarks

This solution illustrates how to use BenchmarkDotNet to run in-depth benchmarking on .NET code.

Concepts that are shown in the solution are listed below.

• Multipe Export Formats (in Release\net5.0\BenchmarkDotNet.Artifacts\results)
• Parameterized Tests
• Example DI Benchmarking

Example

using System;
using System.Security.Cryptography;
using BenchmarkDotNet.Attributes;
using BenchmarkDotNet.Running;

namespace MyBenchmarks
{
    public class Md5VsSha256
    {
        private const int N = 10000;
        private readonly byte[] data;

        private readonly SHA256 sha256 = SHA256.Create();
        private readonly MD5 md5 = MD5.Create();

        public Md5VsSha256()
        {
            data = new byte[N];
            new Random(42).NextBytes(data);
        }

        [Benchmark]
        public byte[] Sha256() => sha256.ComputeHash(data);

        [Benchmark]
        public byte[] Md5() => md5.ComputeHash(data);
    }

    public class Program
    {
        public static void Main(string[] args)
        {
            var summary = BenchmarkRunner.Run(typeof(Program).Assembly);
        }
    }
}
