Improve Performance of Aggregator stage with Decimal output

Aggegator is a typical standard stage to implement Sum or Maximum calculation.
But Sum or Maximum value can be implemented by Transformer stage.
However, the performance of Aggregator stage implementing Sum or Maximum value with Decimal output optional property is much slower than Transformer stage.
Our test jobs show the CPU time of Aggregator is 5.3 times higher than Transformer.
Please improve the performance of Aggregator stage with Decimal output.

The below are the requirements for a patch from the project.
Only any new APTXXX paramater is allowed for the patch defined at DataStage project.
DataStage job compilation should not be required.
