With the buffer pool size of 250 pages, the application test run experienced very poor buffer pool hit ratio of 48.69%.
通过250个页面的缓冲池大小，应用程序测试运行呈现了48.69%的糟糕的缓冲池命中率。
During the test run, the actual amount of buffer pool used did not exceed 1 GB, even though the amount that the server could use was significantly above that.
在测试运行期间，实际使用的缓冲池不超过1GB，尽管服务器可以使用的大小远远超过这个数值。
If each buffer pool has an NPAGES value of -1, then the buffer pool size is being controlled through the BUFFPAGE parameter in the database configuration.
如果每个缓冲池都有一个为“-1”的npages值，那么缓冲池大小是由数据库配置中的BUFFPAGE参数控制的。
