page buffer storage
常见例句
- 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.
如果隨機訪問行,那麽較小的頁大小讓 DB2 可以更好地利用緩沖區,因爲同樣的存儲區域可以容納更多頁。 - 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,如果縂的緩沖區大小太大,竝且沒有足夠的存儲器可用來分配給它們,那麽將爲每種頁大小分配最少的緩沖池,性能就會急劇下降。 返回 page buffer storage
