这种方式的问题是如果这么做反而会减少可用的RAM缓存，而不是增加。

The problem with this approach is that you are actually reducing your available RAM cache, not increasing it.

与优化数据库服务器有所不同，对于NFS来说，您希望允许VMM使用尽可能多的RAM来进行NFS数据缓存。

Unlike when you tune database servers, with NFS you want to allow the VMM to use as much RAM as possible for NFS data caching.

缓存表支持比可用RAM大的数据集，而文本表则可以作为一种导入导出数据的方便手段。

While cached tables provide support for data sets bigger than available RAM, text tables are a convenient way to import and export data.
