We are having one revit MEP license (satand alone) and three Architectural licenses (network). We are here working with local files linked with a central file. and these all files are saving to server. When working with this local file my machine performs very slow and it is hanging some times. But i could understand that if we working with an independent file , this problem will not occur. More over I got an information from one of the revit architecture users that the linking of MEP and architecture is not fair, so this issues are occurring. So please reply a solution for my issue.
