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。
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
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
