    @Options( useCache = false)
    UI2 SelectOne(String id);

}

从结果看，mybatis方式的select比原生态的代码，速度慢两倍，相比dapper而言差距还是很大的。 (https://github.com/StackExchange/dapper-dot-net)

不过两者可比性不大，毕竟不是同一种东西，功能也不一样。

mybatis研究：select性能对比的相关文章

再看ExpressionTree，Emit，反射创建对象性能对比

[前言] 前几日心血来潮想研究着做一个Spring框架,自然地就涉及到了Ioc容器对象创建的问题,研究怎么高性能地创建一个对象.第一联想到了Emit,兴致冲冲写了个Emit创建对象的工厂.在做性能测试的时候,发现居然比反射Activator.CreateInstance方法创建对象毫无优势可言.继而又写了个Expression Tree的对象工厂,发现和Emit不相上下,比起系统反射方法仍然无优势可言. 第一时间查看了园内大神们的研究,例如: Leven 的探究.net对象的创建,质疑<再谈A

一起了解Hibernate与Mybatis的区别优缺点对比

hibernate与mybatis的区别优缺点对比前言: 我是一名java开发人员,hibernate以及mybatis都有过学习,在java面试中也被提及问道过,在项目实践中也应用过,现在对hibernate和mybatis做一下对比,便于大家更好的理解和学习,使自己在做项目中更加得心应手. 第一方面:开发速度的对比就开发速度而言,Hibernate的真正掌握要比Mybatis来得难些.Mybatis框架相对简单很容易上手,但也相对简陋些.个人觉得要用好Mybatis还是首先要先理解好Hi

php+mysql预查询prepare 与普通查询的性能对比

prepare可以解决大访问量的网站给数据库服务器所带来的负载和开销,本文章通过实例向大家介绍预查询prepare与普通查询的性能对比,需要的朋友可以参考一下. 实例代码如下: <?php class timer { public $StartTime = 0; public $StopTime = 0; public $TimeSpent = 0; function start(){ $this->StartTime = microtime(); } function stop(){ $th

java数据库连接池性能对比

这个测试的目的是验证当前常用数据库连接池的性能. testcase Connection conn = dataSource.getConnection(); PreparedStatement stmt = conn.preparedStatement("select 1"); ResultSet rs = stmt.executeQuery(); while (rs.next()) { } rs.close(); stmt.close(); conn.close(); test c

两款JSON类库Jackson与JSON-lib的性能对比(新增第三款测试)

本篇文章主要介绍了"两款JSON类库Jackson与JSON-lib的性能对比(新增第三款测试)",主要涉及到两款JSON类库Jackson与JSON-lib的性能对比(新增第三款测试)方面的内容,对于两款JSON类库Jackson与JSON-lib的性能对比(新增第三款测试)感兴趣的同学可以参考一下. 近日做一些性能优化工作,在挑选JSON类库时,发现除了一般常用的JSON-lib外,还有一款号称性能最快的JSON处理器Jackson,于是用上了刚学会的JMeter,对这两个类库进行

TextFile SequencFile性能对比

首先所有的输入格式都继承FileInputFormat,对于TextFile和SequenceFile有对应的TextInputFormat和SequenceFileInputFormat. 我们先来看一下TextInputFormat的实现: public class TextInputFormat extends FileInputFormat<LongWritable, Text> implements JobConfigurable { private CompressionC

无锁编程与有锁编程的性能对比与分析

最近维护的一个网络服务器遇到性能问题,于是就对原有的程序进行了较大的框架改动.改动最多的是线程工作模式与数据传递方式,最终的结果是改变锁的使用模式.经过一番改进,基本上可以做到 GMb 网卡全速工作处理.在性能达标之后,一度在想有没有什么办法使用更加轻量级锁,或者去掉锁的使用,为此搜索一些相关的研究成果,并做了一些实验来验证这些成果,因而就有这篇文章.希望有做类似工作的同行可以有所借鉴.如果有人也有相关的经验,欢迎和我交流. 1 无锁编程概述本节主要对文献 [1] 进行概括,做一些基础知识的

SQL点滴10—使用with语句来写一个稍微复杂sql语句，附加和子查询的性能对比

原文:SQL点滴10-使用with语句来写一个稍微复杂sql语句,附加和子查询的性能对比今天偶尔看到sql中也有with关键字,好歹也写了几年的sql语句,居然第一次接触,无知啊.看了一位博主的文章,自己添加了一些内容,做了简单的总结,这个语句还是第一次见到,学习了.我从简单到复杂地写,希望高手们不要见笑.下面的sql语句设计到三个表,表的内容我用txt文件复制进去,这里不妨使用上一个随笔介绍的建立端到端的package的方法将这些表导入到数据库中,具体的就不说了. 从这里下载文件employ
