We have SQL Express and Enterprise workgroup. When I import a feature class from a file geodatabase into a new or an existing enterprise geodatabase the file triples in size - on import alone. I'm connection with Esri support but so far they have only been able to replicate my problem, not give me any answers.
The workflow is so basic, all I am doing is moving data from a file gdb to an SDE. Nothing else is happening and my data goes from 118 MB to 585 MB. Compressing has no effect.
