result-buffer 结果缓冲区
If your system has a low buffer pool hit ratio, you can increase the buffer pool size further to achieve better application performance result.
如果您的系统具有较低的缓冲池命中率，您就可以通过增加缓冲池大小来进一步地取得更好的应用程序性能结果。
With the bigger buffer pool of 12000 4k pages, the performance result improves from 43 completed transactions per 10 seconds to 66 completed transactions, as shown in Figure 4.
通过12000个4 K页面的更大缓冲池，性能结果从每10秒完成43个事务增加到完成66个事务，如图4中所示。
However, over-allocating free space may result in wasted DASD space, less data transferred per I/O, less efficient use of buffer pools and more pages to scan.
然而，过多地分配空余空间可能会产生浪费的 DASD 空间，导致每次 I/O 只能传输更少的数据，缓冲池的利用效率更低，并且要扫描更多的页。
