Literally minutes (vs a couple of seconds for a SAP system without all this extra data attached) and it's many thousand objects. It's a large scale system so you have to wonder if this is really that well managed by the CPS architecture..... though I'm generally impressed by CPS, this seems to me to be a weakness they are likely (I hope) to patch. imo the data model/software code should be adjusted so that all these objects are not loaded for more basic functions (like editing SAP system).
We're in touch with SAP and Redwood to look into the best way to manage this.
