[GitHub] [dubbo] tang-bf opened a new issue, #11049: 想要通过SimpleApplicationEventMulticaster自定义线程池提高export 启动速度
tang-bf opened a new issue, #11049:
URL: https://github.com/apache/dubbo/issues/11049
dubbo+spring启动耗时太久，分析发现项目中定义的dubbo service有很多，导致启动过程中SimpleApplicationEventMulticaster执行multicastEvent，循环处理ApplicationListeners时间比较久。所以打算使用线程池excute invokeListener。就会提示端口已被绑定。
请问有什么方法可以加快启动速度吗？
报错信息如下：

如果再同时设置delay,会导致getDeployment().getRegistry() 抛出NPE。报错信息如下：
