After a long session of profiling we have found out, that the main culprit is the loading of the metamodel (a 16 MB ecore file in this instance). I am not entirely sure whether this happens only once during parsing or many times (the different subpackages were referenced multiple times (~100 times) as imports.
The correct solution to me seems to rewrite the package import handling to use the Xtext Index (see also bug 412485)...

Description
It seems that in certain cases (closed sourced development, several huge Ecore models with large number of subpackages, generator.eiqgen used) the resource loading in GenModelMetamodelProviderService.findGenPackages takes up to 90% of the total build time on every save.
