Now let us discuss the issue with the query optimization for the objects which are configured for second level cache.

Second level caching of read-only data is the most efficient followed by non-strict read-write on read-mostly data.

只读数据的二级缓存是最有效的，其次是以读为主的数据的非严格读写。

If tests based on your network and memory configurations show N+ 1 performs better, you can use batch fetching, subselect fetching or second level cache for further optimization.

如果基于你的网络和内存配置的测试表明N+1性能更好，那么你可以使用批量抓取、subselect抓取或二级缓存来做进一步调优。

If we try to eager fetch the department entity then for every fetch of same department the database is hit for department information even though it is available in our second level cache.

如果对department实体采取预先抓取，那么对于同样的department实例，纵使它位于二级缓存中，每次也都需要查询数据库。

The additional CPUs, amount of level two cache, and memory provided better capacity and response time at specific user loads.

额外的CPU、二级缓存量和内存，在特定用户负载下可提供更好的容量和响应时间。

Second level caching is also useful for improving performance of highly transactional applications by caching commonly queried data and avoiding frequently hitting the database.

通过缓存常用查询数据从而避免频繁命中数据库，缓存二级缓存同样有助于提高高事务性应用程序（highly transactional applications）的性能。

Examples are composite keys, legacy databases, prepared statements, complex class hierarchy mappings or Hibernate's first and second level cache.

原因可能出现在以下几个例子中：组合关键字（Composite Keys）、遗留数据库、Prepared Statements、复杂的类层级映射（Complex Class Hierarchy Mapping）或者Hibernate的第一和第二级缓存。
