Windows 7 Beta有改进，但是有多少呢？

Win7之家（ www.win7china.com）：Windows 7 Beta有改进，但是有多少呢？

前几天，有关Windows 7 Beta的一次测试表明其在性能上优胜于XP和Vista。但是测试结果仅仅告诉我们Windows 7是优胜者，但并未明确告诉我们与XP和Vista相比，提升有多少。

来自ZDnet的测试者Adrian Kingsley-Hughes解释称对于一款还处于测试阶段的系统而言，这样的测试并不合适，因为在此阶段开发者们主要注重的是系统的稳定性和可靠性，至于性能方面，则是正式版发布前该做的事情。也就是说，把一款Beta版本的系统和正式版的系统作比较并不合适。

因此，他只是进行了23项测试并简单地标出了谁好谁坏，测试内容主要包括：

*安装Windows 7和Office
*开机和关机
*移动文件（包括磁盘间移动和网络移动）
*解压缩文件
*打开Office和PDF文件
*烧录DVD

最终，显而易见，Windows 7几乎在所有项目中都胜出，极少的几项未显示出优势的项目也是用户很少会使用的功能，比如安装Office和移动大型文件。

对于微软而言，这样的消息显然是大受欢迎。但我们依然得等到正式版时才能断定这些改进有多大以及在可用性方面有何进步。

附部分原文：

The first major independent tests of Windows 7’s beta edition show it outperforming both XP and Vista. However, the method of the testing only shows it is superior and doesn’t accurately tell us the margin of improvement.

The tests come from Adrian Kingsley-Hughes (pictured) of ZDNet. He explained to readers that he didn’t think it was appropriate to carry out the usual computer assessment process known as benchmarking, which uses dedicated software to time how long a particular computer set-up takes to carry out tasks. (These tests produce hard numbers which you might see expressed as, for example, a “3.8 percent improvement”.)

Kingsley-Hughes explains that such testing isn’t really suitable for a beta model, mainly because at that stage developers are more concerned with making sure everything works reliably. Performance tweaks tend to come with the final releases of an operating system, meaning you can’t fairly compare numbers for the Windows 7 beta with finished editions of Windows.

Instead he carried out 23 tests and simply noted which version of Windows performed best and worst. The test included variations on the following tasks:

    * Installing the system itself and Office
    * Boot up and shut down
      Moving files (both from one drive to another and across a network)
    * Compressing and extracting files
    * Opening Office and Adobe Acrobat documents
    * Burning a DVD
