["John Ross (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/ARIES-1359?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

John Ross resolved ARIES-1359.
------------------------------
       Resolution: Fixed
    Fix Version/s:     (was: subsystem-2.0.1)
                       (was: subsystem-core-1.2.0)

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.
