net 6 下性能基准测试

1 安装BenchmarkDotNet 包

2 写两个算法 方法 sha256 和sha512 标记特性

  [MaxColumn,MinColumn,MemoryDiagnoser]
    public class ShaTest
    {
         Testa Testa=new Testa();

        [Benchmark]
        public string Sha256A() => Testa.Sha256("http://www.cndns.com");
        [Benchmark]
        public string Sha512B() => Testa.Sha512("http://www.cndns.com");
    }

3  方法入口处 添加方法

// See https://aka.ms/new-console-template for more information
using BenchmarkDotNet.Attributes;
using BenchmarkDotNet.Running;
using Cndns.Test;

BenchmarkRunner.Run<ShaTest>();
Console.WriteLine("ok");

4  Release  模式下  ctrl+ F5

明显 sha256 用时少。。。
