Without file system caching, Q1 performs similarly on XML and CLOB columns, with a slight disadvantage (10%) for the CLOB column which is not buffered in the buffer pool.
在没有文件系统缓存的情况下，XML和clob列的Q1执行效果类似，不在缓冲池进行缓冲的clob列略微落后(10%)。
Since a DB2 buffer pool is a part of the main memory of the system, the DB2 database manager allocates it for caching tables and index data when it reads or writes to and from media disks.
因为db2缓冲池是系统主内存的一部分，DB 2数据库管理器在它读取或写入磁盘介质时将它分配给缓存表和索引数据。

Increasing the size of this buffer allows the system to map more virtual memory, which results in a lower miss rate for applications that use a lot of virtual memory like Oracle.
增加这个缓冲区的大小允许系统映射更多的虚拟内存，其结果是使得使用大量虚拟内存的应用程序(如Oracle)的缺页率更低。
