我有这样的场景：

  1. ESB 中的代理服务调用服务并接收 2.3 到 4.9MB 之间的有效负载。
  2. 此有效负载有一个人员列表。
  3. 在这个列表中，我使用迭代器调解器对其进行迭代，并在每个元素内部调用 DBReport 调解器将值存储在 Person 元素中。

当有效负载有 2.3MB 时一切正常并且数据在几分钟内存储在我的数据库中，大约 5000 个元素。

但是对于 4.9MB 的有效负载，它真的很慢，因为您可以很快看到 RAM 最多占用 3.0GB 的 2.7。那时，JMX 监控冻结，3 分钟内只有 10000 个元素的 123 条记录存储在数据库中

一段时间后，处理继续并停止一段时间，您可以看到每个 DBReport 调用之间的延迟：

任何想法？

DBReport mediator 在 WSO2 ESB 中同步执行，这意味着执行此 DBReport mediator 的线程被卡住，直到数据库操作完成。这意味着性能低于异步执行时的性能。

因此，为了获得最大的性能，请使用 WSO2 数据服务服务器并使用 DSS 执行插入数据库操作。这样您就可以获得最大的性能。

如果您可以添加配置文件，那就更好了。这将有助于确定此问题的根本原因。
