Dapper ORM VS SqlSugar ORM的 8场对决

由 那年仲夏 提交于 2020-08-20 08:50:29

CUP和.NET SQL版本不同也会存在少许差距，但不会有质变，下面的测试结果仅供参考

比赛规则

1.统一使用Realse版本的最新 DLL,Realse模式启用程序

2.为了平衡CPU和数据库空闲情况，使用车轮战，每场比赛连续10回合比试

3.多次重启电脑取平均成绩上图

比赛成员 

1.SqlSugar 3.1.01

2.Dapper 1.5.0.2  Dapper.Contrib 1.5 官方DLL

 

第一场 ：查询所有  ，主要比拼数据转换实体的性能 

每次查询100万条数据 

 

SqlSugar 100分  Dapper95分

比赛结果： SqlSugar小胜

第八场：比拼普通更新

SqlSugar 90分  Dapper 100分

比赛结果：Dapper小胜

 

总结 

Dapper在批量操作上性能不尽人意，普通查询 增  删 和改 速度可以接受，想了解SqlSugar可以看这篇文章
