ORM到底哪家强？很多人都想知道这个问题，自已也没测试过，只能道听途说。

闲的无聊就将几个ORM拿出来比一比，假如怀疑测试代码有问题可以将它下载下来慢慢研究。

参赛ORM

1、SqlSugar：是一款轻量级的MSSQL ORM ，除了具有媲美ADO的性能外还具有和EF相似简单易用的语法，地址：http://www.cnblogs.com/sunkaixuan/p/5654695.html

2、Chloe ORM：模仿EF代码风格与设计的一款轻量级高性能ORM ，地址：http://www.cnblogs.com/so9527/

3、Dapper ORM : 是一个轻型的ORM类。代码就一个SqlMapper.cs文件,主要是IDbConnection的扩展方法，官方站点http://code.google.com/p/dapper-dot-net/ ，也可以通过Nuget进行安装

4、EF6.0： .NET官方ORM

测试结果：

技术分享

从测试代码可以看出 SqlSugar Dapper Chloe的性能都是差不多的，EF就有些不尽人意

将EF改成AsNoTracking又测了几次，【查询所有】性能有所提升但是还是最慢，查询单条和分页AsNoTracking貌似没什么效果
