This loading takes a long time both because of network bandwidth overhead and session cache overhead (memory consumption and GC pause) if your Hibernate session is stateful.

这种加载需要很多时间，既有网络带宽的原因，如果Hibernate的会话是有状态的，其中也会有会话缓存的原因(内存消耗和GC暂停)。

youdao

Startup time overhead to populate a new cache (which I discuss later in this article) is not significant, as each class simply needs to be relocated into the cache as it is defined.

填充新缓存导致的启动时间开销(在本文后面讨论)并不显著，因为每个类只需在定义时重新定位到缓存中。

The overhead of this request can make a system unscalable if the validating parser does not cache the schema definitions.

如果确认解析器没有对模式定义进行高速缓存，这种请求的开销会使系统失去可扩展性。
