Web Deploy 3.6：防火墙后的性能问题
Web Deploy 3.6: Performance issues behind a firewall
使用 TeamCity 和 WebDeploy，我将网站远程发布到生产服务器。这是一个部署日志示例：

我们将部署代理移到了一台新机器上，但是现在 运行 我们所有站点的 WebDeploy 都有很大的延迟，即使它（有效地）没有部署任何东西也是如此：

第一步 "Using ID [guid] for connections to the remote server" 似乎每次都有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，它不会尝试访问此 IP，所以这是意外的。我们将在下一次维护 window 中尝试修复防火墙规则，让它通过，看看是否可行，但 Web Deploy 在这里试图做什么？
打开 Port 80 以允许 msdeploy.exe 给家里打电话（或者它在那里做什么）修复了 15 秒的延迟问题。部署时间现在缩短到之前机器上的水平（每台服务器 2-3 秒）。
