WSO2AM - 开始很慢
WSO2AM - Starting very slow
我对 wso2am 的启动时间有疑问。我不确定为什么，但启动时间太长。我们已经为它配置了 HA（2 个节点）并且所有数据库都在 Postgres 中。 WSO2AM 版本为 3.1.0.
我们更改了jvm参数（主要是内存）后，它变得非常非常慢，有时需要15分钟以上才能启动，而通常需要1分钟。
如果您愿意，我可以分享日志的摘录或其他一些属性。启动 webapps 需要花费大部分时间，如下所示

抱歉，我没有更多信息，但我完全不知道要检查什么。

我可以找到根本原因。
我们已经在 AWS 上使用 EFS 实现它来共享 deployment/server 目录来完成 WSO2AM HA 要求。
由于 EFS 上配置的吞吐量类型（突发模式），它限制了 IO，因此启动需要太多时间。提供的最大 IO 为 4KiB（Bursting 模式与 IO 之间有关系 space 你使用了多少）。
我们的解决方案是创建一个新实例，在内部配置 NFS 服务，然后通过这种方式解决。您也可以将 EFS 配置为预配置吞吐量模式，但这对我们来说太贵了。
