If rows are accessed randomly, then the smaller page size enables DB2 to make better use of the buffer, because more pages fit into the same storage area.
如果随机访问行，那么较小的页大小让db2可以更好地利用缓冲区，因为同样的存储区域可以容纳更多页。
A buffer pool is an area of storage in memory into which database pages (containing table rows or index entries) are temporarily read and changed.
缓冲池是内存中的一块存储区域，用于临时读入和更改数据库页(包含表行或索引项)。
In addition to this, the main area of water can still offer a reserve of 15 centimetres between the normal and the maximum water level, which provides a storage buffer of 1,300 cubic metres.
另外，在常水位与高水位之间，设计中的主体水面能够提供15厘米高度的水量存留，这样便提供了1300立方的缓冲蓄水能力。
