If you use multiple buffer pools, you might take the buffer pool hit ratio together with the buffer pool name from the PWH.BUFFERPOOL table.
若使用多个缓冲池，可能要从PWH . BUFFER pool表取得缓冲池命中率和缓冲池名称。
When multiple buffer pools are in use, the buffer pool snapshot data can be used to calculate the buffer pool hit ratio of each pool to indicate the effectiveness of each buffer pool.
当多个缓冲池同时在用时，缓冲池快照数据可用于计算每个缓冲池的命中率，来表示每个缓冲池的有效性。
Configuration changes to the buffer pool, the use of multiple servers, and even the use of RAM disk showed that changes in how memory was configured could help overall performance.
改变缓冲池、使用多个服务器，甚至使用RAM磁盘，这都表明改变内存的配置能够提升总体性能。
