However, if you make it too large, you can waste valuable memory resources on your managed system due to the size of the page table created for the partition.
然而,如果将它设置的太大,则可能会由于为该分区创建的页表大小而浪费所管理系统上的宝贵内存资源。
For example, say that you cannot afford to have large buffer pools due to memory constraints on the test system and would like to configure the size the same without actually having them in reality.
例如,假设由于测试系统上的内存约束,您无法获得大型的缓冲池,并且希望将大小配置得相同,实际上却不是真正有这么大。
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。
