再续NBear性能测试:ADO.NET, NBearV3, NHibernateV1, NBearLite, NBearLite+NBearMapping性能比较[2008/1/3修订:NBearLite更新至v1.0.1.0整合NBearMapping版地测试结果]

本测试对ADO.NET, NBearV3, NHibernateV1, NBearLite, NBearLite+NBearMapping进行了常见的读写测试。本测试证实了try兄之前对NBearV3的性能问题的测试,应该是正确的。NBearV3的3.7X版本,在升级过程中引入一定的性能损失,该性能损失在3.6X应该不存在,我会检查真正的原因。(7/26修订:NBearV3的性能问题已修复,是因为一个很小的代码语句造成的。)本测试同时证实,NBearLite及NBearLite+NBearMapping的ORM方案,平均性能有很大改善。

(7/26修订:代码已更新为修正NBearV3性能问题后的版本)
2008/1/3修订:NBearLite更新至v1.0.1.0整合NBearMapping版本)

(运行该示例前请修改App.config中的connectionstring,并在tempdb数据库中执行sql目录中的db.sql和data.sql初始化测试数据)

测试内容:

本测试分别测试了小数据两读取、大数据两读取和写操作,返回数据分别填充到DataSet或实体类。
