Shared memory is well suited to larger collections of data and, because it uses memory, grants fast, random access.

共享内存适合比较大的数据集，因为它使用内存，支持快速的随机访问。

A good starting point is to select the default (4 KB), especially if row sizes are fairly small or when access to the data is primarily random.

一开始的时候，可以选择默认选项(4 KB)，如果行的长度很小，或者对数据的访问基本上是随机的，则更应该选择这一选项。

And AgigA Tech makes so-called non-volatile Random Access Memory (RAM) that helps people store and retrieve rapidly changing data far more quickly than the slow-poke disk drive technology that keeps data centers humming.
