本文提供的技术能有效地降低程序的争用代价，并增大程序在出现非线性伸缩行为之前所能承受的负载。

The techniques presented in this article are effective for reducing the cost of contention in your programs, and increasing the load they can bear before exhibiting nonlinear scaling behavior.

对于所有这些情况，驻留在相同的队列管理器上的集群和应用程序是直接争用资源的。

In all of these cases, the cluster and the applications are in direct competition when they are hosted on the same queue manager.

但在应用这些技术之前，您必须首先分析您的程序，以判断哪里可能出现争用。

But before you can apply these techniques, you first have to analyze your program to determine where contention is likely to occur.
