使用 TeamCity 和 WebDeploy，我将网站远程发布到生产服务器。这是部署的示例日志：

我们将部署代理移到了新机器上，但现在在我们所有站点上运行 WebDeploy 时出现了巨大的延迟，即使它（有效地）没有部署任何东西：

第一个“使用 ID [guid] 连接到远程服务器”步骤似乎每次都有一个非常可预测且一致的 15 秒延迟。
使用 NETSTAT，这条信息脱颖而出：
TCP 192.168.XXX.XXX:58265 23.47.144.26:80 SYN_SENT
[msdeploy.exe]
在旧机器上，它不会尝试访问这个 IP，所以这是出乎意料的。我们将尝试在下一个维护窗口中修复防火墙规则，让它通过，看看这是否可行，但 Web Deploy 在这里试图做什么？
