备注

已更新的文本：2006 年 7 月 17 日

Optimized mode improves performance by removing unused columns, outputs, and components from the execution plan of the data flow task.

注意：
A property with the same name, RunInOptimizedMode, can be set at the project level of an Integration Services project to indicate that the Data Flow task runs in optimized mode during debugging. This property overrides the RunInOptimizedMode property of Data Flow tasks in the packages in the project. The value of the project property is False by default.

For a brief discussion of properties that can be used to optimize the performance of the Data Flow task, see 包性能故障排除.
