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)...

Pushing these issues to the 1.2 timeframe.

Replaced target milestone from incquery with VIATRA

Postponed issues to 1.3

1.3 M1 already passed.

Not realistic for 1.3.
However, as this feature highlight a major performance bottlenecks in case of complex domains, I have tentatively raised its priority for 1.4.

Today I had another session where I have found cases where metamodel resolution is slow (more specifically, it took about 15 second to load the VQL editor, and about 8-9 seconds were loading the metamodel repeatedly), and while looking at the details I have seen two areas to research that might improve the performance:
1) Instead of loading the metamodels into the ResourceSet used by the editors, TargetPlatformMetamodelIndex could maintain its own ResourceSet, and load the metamodels there. This way the metamodels needs to be reloaded only once, and then references will become cheaper. However, the usual when to dismiss results problems will still occur. 2) The PluginModelManager used inside the TargetPlatformMetamodelIndex has listener support called IPluginModelListener and IStateDeltaListener. These might be useful for implementing a non-experimental caching that would improve resolution speed for large/complex metamodels.

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.
