Thanks for the report and patch. We were able to discern a 25% improvement using the idea of caching already processed constituents.

> Two improvements in the patch
> 1) Application subsystems are not processed by the method because application subsystems do not share capabilities. (I think it works like that but maybe I'm wrongly interpreting the specification)
> 2) All processed constituents are stored in a set and not processed again when encountered in a different subsystem when they are being shared across features. When using 60 features a shared bundle used to be processed 60 times.
