有使用两个典型原因过程当组更改（高级）。第一个是有意识地在组要被处理（并且已经如此命令）传入的数据。在这种情况下，结构使然集团通过使用 - 而不是性能方面的考虑。

第二个原因可能是潜在的性能提升。

性能数据时最有可能 already sorted (or read using aSQL ORDER BYstatement) since less work is required of FME.如果 the data needs ordering, it can be sorted in the workspace (though the added processing overhead may negate any gains).

Sorting becomes more difficult according to the number of data streams.Multiple streams of data could be almost impossible to sort into the correct order, since all features matching a通过...分组value need to arrive before any features (of any feature type or dataset) belonging to the next group.In this case, using通过...分组with过程在结束（封闭）may be the equivalent and simpler approach.

Note:Multiple feature types and features from multiple datasets will not generally naturally occur in the correct order.

As with many scenarios, testing different approaches in your workspace with your data is the only definitive way to identify performance gains.
