We've noticed a gradual reduction in performance when checking out the master composition model from our ProjectWise Managed Workspace. We've already upgraded to the latest ProjectWise CONNECT Edition Update 3.1 release but it does not seem to make any difference, with files still taking 6-7 minutes to load.
One particular DGN file was causing this performance lag as it contained: 3D model geometry, 25 Drawing Models, more than 40 Dynamic Views (Saved Views with link sets) along with over 80 reference attachments. When this file was removed from the reference chain the master composition model and remaining reference attachments took approximately one minute to open.
It is likely that ProjectWise is anticipating everything required to load all of the models, links and references from that DGN file by using data from fileinfo.xml, resulting in this performance lag. In order to reduce this load time it is suggested that the purposes of this one DGN file be better federated; e.g., extract Saved Views and Drawing Models into other/multiple DGN files specific to that purpose.
