Memory impacts the number of client connections and the size of the buffer pool and database cache allocated by the server.

内存影响客户端连接的数量、缓冲池的大小，以及服务器分配的数据库缓存的大小。

This difference in performance gain is predictable because the pressure on the TLB cache increases as the size of the database and the memory assigned to the DB2 buffer pools increases.

这两组测试得到的性能结果的不同是可以预测的，因为随着数据库和分配给db2缓冲池的内存的增加，TLB缓存上的压力也随之增加。

Identify problems with memory, including low buffer pool hit ratios, catalog cache hit ratios, and package cache hit ratios.

识别内存问题，包括较低的缓冲池命中率、较低的目录缓存命中率和较低的包缓存命中率。
