Windows 7 Beta有改進，但是有多少呢？

Win7之家（ afsion.com.cn）：Windows 7 Beta有改進，但是有多少呢？

前幾天，有關Windows 7 Beta的一次測試表明其在性能上優(yōu)勝于XP和Vista。但是測試結果僅僅告訴我們Windows 7是優(yōu)勝者，但并未明確告訴我們與XP和Vista相比，提升有多少。

來自ZDnet的測試者Adrian Kingsley-Hughes解釋稱對于一款還處于測試階段的系統(tǒng)而言，這樣的測試并不合適，因為在此階段開發(fā)者們主要注重的是系統(tǒng)的穩(wěn)定性和可靠性，至于性能方面，則是正式版發(fā)布前該做的事情。也就是說，把一款Beta版本的系統(tǒng)和正式版的系統(tǒng)作比較并不合適。

因此，他只是進行了23項測試并簡單地標出了誰好誰壞，測試內容主要包括：

*安裝Windows 7和Office
*開機和關機
*移動文件（包括磁盤間移動和網絡移動）
*解壓縮文件
*打開Office和PDF文件
*燒錄DVD

最終，顯而易見，Windows 7幾乎在所有項目中都勝出，極少的幾項未顯示出優(yōu)勢的項目也是用戶很少會使用的功能，比如安裝Office和移動大型文件。

對于微軟而言，這樣的消息顯然是大受歡迎。但我們依然得等到正式版時才能斷定這些改進有多大以及在可用性方面有何進步。

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
