主题：【业界动态】.NET击败了J2EE -- Highway

具体地说，是Windows 2003 + MS.NET 1.1击败了J2EE的领头羊 IBM WebSphere + Linux.

在最近由Middleware 公司进行的一次全面研究测试中，Windows 2003 + MS.NET 1.1以较大优势全面击败了Linux + WebSphere组合。这个研究测试非常的具体，是以一个具体的工程项目为对象，非别用两种不同的技术来实现，最后全面对比开发效率，发布维护复杂度，运行性能和稳定性等等。整个测试的全部文档包括源程序都对外公开，如果你觉得有问题，可以提出质疑。（以前微软曾经将Sun的J2EE的Demo Project-- Pet Shop用.NET重写了一遍，宣称性能提高了150倍。当然那是一个比较小的项目，有多少代表性很难说，业界对那个结果也不是很重视。但这次这个报告份量要重得多！）

如果对现代WEB开发有兴趣的朋友可以好好研究一下这些文档，非常的详细和专业，覆盖了一个具体项目的全部阶段。这里是具体网址！

[SIZE=3]Comparing Microsoft .NET and IBM WebSphere/J2EE:[/SIZE]

A Productivity, Performance, Reliability and Manageability Analysis

This endeavor is a massive study that compares IBM WebSphere / J2EE against Microsoft .NET on a number of dimensions: developer productivity, manageability, reliability and application performance. 

To conduct the study, The Middleware Company assembled two independent teams, one for J2EE using IBM WebSphere, the other for Microsoft .NET. Each team received the same specification for a loosely-coupled system to be developed, deployed, tuned and tested in a controlled laboratory setting. The WebSphere team developed two different implementations of the specification, one using IBM's model-driven tool Rational Rapid Developer (RRD), the other with IBM's code-centric tool WebSphere Studio Application Developer (WSAD). The .NET team developed its single implementation using Visual Studio.NET as the primary development tool.
