内网服务连接外网阿里云上部署的100台服务启动时间超长（5分钟以上） #10763

整体架构是内网跟外网有2个zk作为注册中心，外网的服务注册到外网zk上面，内网的服务分别连接内网和外网的zk

内网服务在启动的时候时间很长，基本上要5分钟左右才能完全启动成功，想知道为什么会要这么长的时间启动？

是Spring Boot应用，Spring Boot是2.2.10.RELEASE版本，Dubbo是3.1.1版本

看这日志他是会去连接我外网的100台服务器吗？要等100台服务器都连接成功了才能完全启动？在这之前整个服务都是无法提供服务的，http端口也访问不了

外网 zk 的网络时延多高。Dubbo 是采用懒加载去建连接的
