Increase the size of the log buffer area if there is considerable read activity on a dedicated log disk, or there is high disk utilization.
如果在某个专用的日志磁盘上存在大量的读活动，或者具有较高的磁盘利用率，就增加日志缓冲区域的大小。
With different trace levels set for various registrations, the influx of data into the buffer also depends on the amount of activity in each connection being traced.
通过为各种不同注册设置不同跟踪等级，数据进入缓冲区还依赖于在每个被跟踪的连接中的活动数量。
If the buffer pool is large enough to keep the required data in memory, less disk activity will occur.
如果缓冲池大到足以在内存中保存所需数据，就会发生较少磁盘活动。
