我在wso2am的启动时间上遇到问题。我不知道为什么，但是启动时间太长。我们为它配置了HA（2个节点），所有数据库都在Postgres中。 WSO2AM版本是3.1.0。
更改了jvm参数（基本上是内存）后，它的运行速度非常慢，有时通常需要1分钟才能启动，因此要花费15分钟以上的时间。 如果需要，我可以共享日志的摘录或其他一些属性。正如您在下面看到的，启动Web应用程序需要花费大量时间

抱歉，我没有更多信息，但是我完全迷失了要检查的内容。
谢谢！

我可以找到根本原因。 我们已经在AWS上使用EFS来实现它，以共享部署/服务器目录来满足WSO2AM HA要求。 由于EFS（突发模式）上配置的吞吐量类型，它限制了IO，因此启动会花费太多时间。预配置的最大IO为4KiB（突发模式在IO和您使用的空间之间有一定的关系。）
我们的解决方案是创建一个新实例，在其中配置NFS服务并通过这种方式解决。您也可以将EFS配置为预配置的吞吐量模式，但这对我们来说太昂贵了。
