質(zhì)疑InfoWorld的Windows 7評測

Win7之家（ afsion.com.cn）：質(zhì)疑InfoWorld的Windows 7評測

 我們知道自從Windows 7有版本泄露開始，已經(jīng)有不少人對其進行了測試，而其中比較著名的就是InfoWorld的測試了。而國外某IT寫手顯然對該評測不太贊同并提出了幾點異議。

*第一點我要質(zhì)疑的就是測試中所用的工具-DMS Clarity Studio。事實上，我并不認為這是一款比較實用的測試工具，雖然它也能提供不少詳細的數(shù)據(jù)，但作為單獨的測試軟件，我就對其測試結(jié)果有些懷疑了。除此之外，有太多可用的測試軟件了。
*對于測試中線程數(shù)的計算方式我很是不理解，本來從操作系統(tǒng)中統(tǒng)計線程數(shù)就并非易事，而隨后得出的結(jié)論就更加幼稚了。
*公平地說，僅僅從進程列表中來決定系統(tǒng)究竟做了哪些改變顯然是不可取的。
*內(nèi)存占用測試也并不可靠，以不同大小的內(nèi)存來測試同一款系統(tǒng)的內(nèi)存占用顯然要更好。
*至于測試中提及的兼容性問題那就更滑稽了。Windows 7現(xiàn)在還只是pre-beta階段，而在Windows 7 RTM之前，像Skype和Daemon tools這樣的軟件還不知道要更新多少次。不過，兼容性確實是微軟必須重點關(guān)注的問題之一。
*最后，測試中用的是Windows 7 Build 6801，這版本已經(jīng)很老了。一旦某個新版本出現(xiàn)了，之前你從舊版上收集的數(shù)據(jù)也就失效了。

附部分原文：

    * My first issue is with Kennedy’s choice of benchmark tool - DMS Clarity Studio. Bottom line, I have trouble accepting this tool as a valid benchmark. OK, as part of a comprehensive roundup, this tool does provide a useful data point, but when used alone I view it with suspicion. There are far more established benchmark suites that can be used.
    * I don’t understand Kennedy’s obsession with thread count. There’s very little that you can take away from totting up the OS thread count, and to jump to the conclusion that more threads is bad is naive. You might as well throw a cup of tea into the PC and read the leaves.
    * Equally, looking at process lists to try to determine how much the OS has changed is pointless.
    * RAM consumption is also a weak metric. It would be better to benchmark the same system with different amounts of memory installed. That tells you far more about how the OS uses the available RAM.
    * The compatibility issues that are raised in the article are interesting, but it’s important to remember that Windows 7 is in a pre-beta state and that apps like Skype and Daemon Tools will probably be updated many times before Windows 7 goes RTM. However, application compatibility is something that Microsoft needs to keep a very close eye on.
    * From the comments it seems that Kennedy is testing build 6801 of Windows 7. This is a pretty old build. Once a new build is released any data you collected from old builds is instantly obsolete.
