Higher Settings may improve performance but raise the number of connections to the data source.
较高的设置可能会提高性能，但增加数据源连接数。
Increasing the number of threads in the thread pool has limited benefit because application-server performance starts to degrade as the number of threads in the pool increases.
增加线程池中的线程数量收效甚微，因为当线程池中的线程数量增加时，应用程序-服务器性能将开始降低。
For best performance, you should specify the same number of processes as the number of replicates in the replicate set.
为了获得最佳性能，指定的进程数应该与复制集中的复制数一致。
This technique can significantly improve performance because it cuts down on the number of I/O requests.
该技术可以大大提高性能，因为它减少了I/O 请求的数量。
