这两天在对一些ORM进行性能测试(涉及SqlSugar、FreeSql、Fast.Framework、Dapper.LiteSql)，测试用的是Winform程序，别人第一眼看到我的程序，说，你这测试没意义！
可能我的测试程序的某些地方写的比较变态吧，但我认为有现实意义，并且网上有相关网站崩溃问题的文章，那什么“爆高分析”，“崩溃问题”，WinDbg用的很6，那写程序阶段为什么没发现呢？
场景
假设WebApi(或者说网站后台服务)正在被高并发访问，一段时间后，服务的线程数量达到了200及以上，那么.NET的线程池，如果线程处于空闲状态，默认是20秒后释放线程，假设这200多个线程空闲了，但是还没有达到空闲20秒的时间，还没有释放，如果此时，又有大量高并发的访问，200个线程去操作数据库，那就可能很危险了。
关于性能
虽然代码写的可能有点变态，但我的测试不是很严格，也不是很规范。
性能如果不是数量级的差，问题都不大，比如一个是0.8秒，一个是1.8秒，那1.8秒的慢是慢了一点，但问题不大；但如果一个是0.8秒，一个是10秒，那10秒的这个，可能就有点问题了，即使别人用的Emit你用的反射，也不应该差这么多。
当然了，我的测试，数据规模不大，10000条，button可能会点10次，那也才10万数据量，在数据量方面我没有做极端测试，我的重点不是这个，因为很少会去查100万数据到内存中，就暂不讨论这个。
这个测试除了大体上测试一下性能，主要就是增加了并发测试。
非并发性能测试的截图我就不放全了，这几个ORM有差别，但我觉得2秒3秒还是6秒甚至8秒，都问题不大的，都算差不多，都算堪用。
测试代码
测试数据库是MySQL，MySql.Data.dll目前用的是最新的8.0.30版本(题外话，它里面的异步是假异步，把同步方法包装成的异步，我说怎么反而慢了呢，真异步要使用MySqlConnector.dll，Fast.Framework使用的是这个性能很好)。
1. 数据库连接字符串
server=localhost;database=sqlsugar_test;user id=root;password=123456;character set=utf8mb4;
这里没有设置min pool size和max pool size，也没有设置connection timeout，没有设置的话connection timeout默认是15秒。
2. 在写Winform做高并发测试的时候，有个参数可能需要设置
<system.net>
<connectionManagement>
<add address="*" maxconnection="1200" />
</connectionManagement>
</system.net>
测试高并发网络请求的时候，要设置这个，那么数据库增删改查要不要设置呢？反正就一个参数，加或不加，可以试试。
3. 实体类
以SqlSugar的为例吧，几种ORM测试用的表结构是相同的。
using System;
using System.Linq;
using System.Text;
using SqlSugar;
namespace Models
{
///<summary>
///用户表
///</summary>
[SugarTable("sys_user")]
public partial class SysUser
{
public SysUser(){
}
/// <summary>
/// Desc:主键
/// Default:
/// Nullable:False
/// </summary>
[SugarColumn(IsPrimaryKey=true,IsIdentity=true,ColumnName="id")]
public long Id {get;set;}
/// <summary>
/// Desc:用户名
/// Default:
/// Nullable:False
/// </summary>
[SugarColumn(ColumnName="user_name")]
public string UserName {get;set;}
/// <summary>
/// Desc:用户姓名
/// Default:
/// Nullable:True
/// </summary>
[SugarColumn(ColumnName="real_name")]
public string RealName {get;set;}
/// <summary>
/// Desc:用户密码
/// Default:
/// Nullable:False
/// </summary>
[SugarColumn(ColumnName="password")]
public string Password {get;set;}
/// <summary>
/// Desc:备注
/// Default:
/// Nullable:True
/// </summary>
[SugarColumn(ColumnName="remark")]
public string Remark {get;set;}
/// <summary>
/// Desc:创建者ID
/// Default:
/// Nullable:False
/// </summary>
[SugarColumn(ColumnName="create_userid")]
public string CreateUserid {get;set;}
/// <summary>
/// Desc:创建时间
/// Default:
/// Nullable:False
/// </summary>
[SugarColumn(ColumnName="create_time")]
public DateTime CreateTime {get;set;}
/// <summary>
/// Desc:更新者ID
/// Default:
/// Nullable:True
/// </summary>
[SugarColumn(ColumnName="update_userid")]
public string UpdateUserid {get;set;}
/// <summary>
/// Desc:更新时间
/// Default:
/// Nullable:True
/// </summary>
[SugarColumn(ColumnName="update_time")]
public DateTime? UpdateTime {get;set;}
}
}

部分测试结果
循环插入、循环修改和查询
真的差不多。
并发插入，全部通过
Fast.Framework还在优化我用的临时版本
SqlSugar和Fast.Framework的测试结果，就是我这篇博客要讲的的重点了，并发，肯定要加锁，并发大的时候，锁们可能在相互等待，干一会活，歇一会，导致白白浪费几秒，甚至几十秒。
正常的是类似这样的，任务来了，就干活：
不正常的是类似这样的(我写的Dapper.LiteSql，以前是使用using的没问题，后来为了干掉using，就加了连接池，就用到锁，锁的颗粒度大，就是像下面这样样子，比这还过份，后来把锁的粒度搞小一点，有改善，但还是不行，最后接着优化，除了用线程安全队列外(它底层也是锁)，能不用锁就不用锁(有时候不用锁实现不了功能，又必须用)，就解决了这个问题)：
耗时的全是外部调用：
并发查询测试
