FileSystemResourceManager.resourceForLocation was identified to be slow in bug 564569 / bug 535681
For files=true the algorithm searches currently in all projects for a file. Which is bad if many projects in workspace.
I do not yet understand what the real purpose of FileSystemResourceManager.resourceForLocation is but i got the strong feeling instead of travsersing all projects it should be faster to ask Workspace.getAliasManager().findResources() for all related resources instead.

Am i on the wrong track?
