WebDeploy3.6:防火墙背后的性能问题
WebDeploy3.6:防火墙背后的性能问题
提问于 2017-09-02 00:46:58
使用TeamCity和WebDeploy，我将网站远程发布到生产服务器。下面是一个部署的示例日志：

利用NETSTAT，这一信息非常突出：
TCP 192.168.XXX.XXX:58265 23.47.144.26:80 SYN_SENT
[msdeploy.exe] 在旧机器上，它不尝试访问这个IP，所以这是意外的。我们将尝试在我们的下一个维护窗口中修复防火墙规则，让它通过，看看它是否有效，但是Web部署在这里试图做什么呢？

打开Port 80允许msdeploy.exe打电话回家(或者不管它在做什么)修复15秒的延迟问题。部署时间现在减少到上一台机器上看到的情况(每台服务器2-3秒)。
