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
<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<OutputType>Exe</OutputType>
<TargetFramework>netcoreapp2.0</TargetFramework>
</PropertyGroup>
<ItemGroup>
<PackageReference Include="BenchmarkDotNet" Version="0.11.5" />
</ItemGroup>
</Project>
构建&&运行
- 构建
docker-compose up
- 效果
