最近我遇到了一个奇怪的问题,有时浏览器需要大约20秒才能建立到IIS web服务器的连接

1. this cannot be repro each time, when successful access the site, the following connecting will be very fast. After restart Application pool and Web Site, the first time connect will be slow.<br>
2. When success gernerate connection success, after minutes, the establsh connection will getting slow again.<br>
3. this is not relate to authentication, both Windows Authentication and Anonmymous will have the same problem.<br>
4. Installed HTTPWatch on my client machine, it shows that 20 seconds is connecting time before wating when this problem happen.<br>
5. localhost cannot repro, each time establish connection is fast
1。这不能每次重新编程,当成功访问站点时,以下连接将非常快。重新启动应用程序池和网站后,第一次连接将变慢。
2.成功生成连接成功后,分钟后,建立连接将再次变慢。
3.这与身份验证无关,Windows身份验证和Anonymous都会有相同的问题。
4.在我的客户端计算机上安装了HTTPWatch,它显示出现此问题时,在等待之前的连接时间为20秒。
5.localhost无法重新编程,每次建立连接都很快
从IIS的日志中,第一个请求是get after


如何调试这个?这似乎与网络、porxy、域有关,是否有一些工具可以帮助诊断此问题,并可以告诉我在建立连接的时间段内服务器在做什么
