您可以使用快照来获得诸如缓冲池命中率、排序堆溢出的次数以及系统工作负载之类的信息。

You can use the snapshot report to derive information such as the buffer pool hit ratio, amount of sort heap overflows, and the system workload.

在解决应用编程问题时，为了达到合适的反应次数，你必须使用数据缓冲存储。

To achieve acceptable response times when solving some application programming problems you must cache data.

日志记录器提供更详细的信息并采用xml格式而不是一般文本；由于第一次数据捕捉失败，所以它还将此数据的子集记录进内存中的缓冲区。

The logger provides more detailed information and presents it in an XML format rather than as flat text; it also traces a subset of this data into an in-memory buffer for first failure data capture.
