并行交换结构能够极大提升网络设备的交换能力，使网络设备拥有更高的交换容量和交换速率，以支持更多的网络业务。
Parallel switches highly improve the switching capability of network equipments that means higher switching capacity, higher switching speed and more networks services.
我们也能发现这些活动是并行的，通常高效的，跨功能的交换信息和工作成果——就像RUP中那样。
We also see that the activities run in parallel, typically exchanging information and work packages in a highly efficient, cross-functional manner -- just like in the RUP.
然而，任务再无法并行运行，或使用多个CPU，它会使用更少的内存，并会运行得更快，因为InfoSphere DataStage服务器不需要再进行内存交换。
While the job will no longer run in parallel, or use multiple CPUs, it will use less memory and run faster because the InfoSphere DataStage server no longer has to swap.
