本文将介绍如何确定造成性能下降的潜在原因。
This article shows how to locate potential causes of performance degradation.
因此，造成性能下降的根本原因是因为Bank服务的响应时间较慢，这属于外部服务问题。
So the root cause for this performance degradation problem is the slow response time from Bank service, which is an external service problem.
这会造成性能的下降：越来越多的时间和带宽花在了在集群中维护会话备份的一致性，而不是用来处理用户请求。
This causes degraded performance as increasing amounts of time and bandwidth are absorbed in maintaining consistency of session backups across the cluster rather than processing user requests.
这会造成性能急剧下降，并且服务器响应时间会加长。
This would cause major performance degradation, and lead to longer response times from the server.
通常，如果表中的数据极少，扫描不致于造成性能显著下降，则可以禁止显示性能问题。
In general, you might suppress a performance issue if the table contains so little data that a scan will not cause performance to drop significantly.
