This method is called when I select folder of my NBM project to find all files belonging to some NBM that is part of platform. It parses update tracking file with DOM and then traverses its elements to build the results. It should be faster to do it SAX - the structure of document is very simple and we can avoid a lot of garbage that is created.
Creating of files from strings is reasonably fast except modules like bundled Tomcat that contains huge number of file. BTW: why we need these information? Or why we need them while project is opening?
I know SAX would be faster. The info is probably not needed during project opening as such, but it may be needed later when the project is being edited, mainly for code completion. Could be deferred/optimized in various ways. No time to work on it yet.

I can help at least with SAX utilization phase.
Created attachment 27240 [details] SAX patch which is strangly slower then the current DOM implementation
Attaching patch we were examining here. To try it run e.g. ModuleListTest.testExternalEntries().
Any news Radime? Should we switch to good-manner behaviour (SAX) or stay with currently (surprisingly) fastest implementation (DOM).
Three weeks without feedback. Let's stay with DOM when is is even faster then SAX. Not closing yet since Jesse might have some ideas ("Could be deferred/optimized in various ways.") But main Radim's point was considered --> P4
When the optimization mentioned by issue #114155 is active, this method is not called (unless you e.g. use the Add Module Dependency dialog, when dependent modules need to be scanned in more detail anyway).
