benchmarkdotnet docker 运行

使用docker 运行基准测试是一个不错的选择，可以减少我们环境搭建的时间，同时也可以加速ci/cd

环境准备

• docker-compose 文件

version: "3"

services: 

  app-benchmark:

    build: 

      context: ./

      dockerfile: Dockerfile-benchmark

    image: dalongrong/dotnetcorebenchmark-demo:alpine

• dockerfile

FROM mcr.microsoft.com/dotnet/core/sdk:2.2 AS build

WORKDIR /app

COPY benchmark/*.csproj ./

RUN dotnet restore

COPY benchmark/. /app/

ENTRYPOINT [ "dotnet","run","-c","Release" ]

代码准备

注意target版本dotnetcore2.0

• 创建demo项目

mkdir benchmark

cd benchmark

dotnet new console

• 添加依赖库

dotnet add package BenchmarkDotNet

• 简单demo

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<Md5VsSha256>();

        }

    }

}

 

 

• demo 的benchmark.csproj
