However, if the total buffer size is too large, and there is not enough storage to allocate them, a minimum system buffer pool for each page size is allocated, and performance is sharply reduced.
但是，如果总的缓冲区大小太大，并且没有足够的存储器可用来分配给它们，那么将为每种页大小分配最少的缓冲池，性能就会急剧下降。
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。
