what size measure do you need? Data files size in GB, count of objects in the database?
I just run various tests on smaller databases and bigger ones (considering database size in GB and objects count), but I do not have a clear sight what the problem might by. I guess it's not the size in GB but the object count. Perhaps it depends on how many procedures, functions, views (= objects with a source code) exist within the database.
Please let me know if there is any measure that I may count and report (e.g. from sys.objects).
