.NET 之 ORM 性能评测

.NET 之 ORM 性能评测

Why

  1. 你应该总能听到某ORM性能比Dapper高
  2. 你应该有如下疑问：
    1. 基准测试是否权威
    2. 基准测试的方式是否合理
    3. 基准测试的标准是否能够统一
    4. 统一基准测试标准/规范

如何进行姿势正确的性能测试

相信大家对 Dapper 的性能，以及基准测试的权威性是没有疑问的（否则不会有那么多ORM在做性能测试的时候直接选型Dapper）,那么我们就使用 Dapper 性能基准测试 来作为我们的基准测试模板，并加入一些没有纳入基准测试的 ORM 。这样从合理性/可信度就大体有了一个标准和保障。

接下来 fork Dapper GitHub 仓库，并添加了 SmartSql/IBatis.Net/FreeSql/SqlSugar/Chloe

源代码地址：https://github.com/Ahoo-Wang/Dapper,如对测试结果，测试方法有疑问请给我提交issue。

如何自己进行以上基准测试

强烈建议读者按照以下步骤自己运行基准测试。

  1. Git-Clone https://github.com/Ahoo-Wang/Dapper
  2. cd Dapper/Dapper.Tests.Performance
  3. dotnet publish -c release
  4. 运行 Dapper.Tests.Performance.exe
  5. 提示输入，请输入 "*" 运行所有基准测试
  6. 等待测试结果，目录：BenchmarkDotNet.Artifacts 下会有一个日志文件，和 results 文件夹 (测试结果文件存放在此目录)

基准测试结果

重要提示：FreeSql/SqlSugar 官方nuget包为非Release版本，所以测试结果会有影响，仅供参考。
