您回复好快。；-）
NT5 增加的新功能太多，实在说不过来。
但我想您也许对其中 IIS5 的新特性会关心。我有一个旧帖子谈过。
您可查阅。
另外，关于安全性，有一个新东西叫 security configuration utility 之类的，是一个 MMC SNAP-IN 插件。我还没细看，不知是否只对 NT5 有效。
下面我列举几篇有关 perf.的供您参考。
原文是 HTML 的，所以得麻烦您转化一下，但里面就有 LINK 了。

============================================
有关安全性的文章我还在收集中。
我知道有一次有人抱怨 IIS 慢，我的同事根据 high volumn 一文梢做配置调整后， IIS 静态发布能力提高至原来 3 倍以上，还有潜力可挖。
所以请您留意一下上面列举的文章。谢谢。
