You are not using your KEEP pool to cache frequently referenced tables and indexes. This may cause . When configured properly, the KEEP pool guarantees full caching of popular tables and indexes. Remember, an average buffer get is often 100 times faster than a disk read. Any table or index that consumes > 10% of the data buffer, or tables & indexes that have > 50% of their blocks residing in the data buffer should be cached into the KEEP pool. You can fully automate this process .

對使用KEEP池的建議:對於任何消耗10%data buffer的表或索引,或者任何表或索引的50%資料塊在data buffer池裡,都建議應該儲存在KEEP池裡。
