Hi Jaco,

We are working on a guidance paper here that I hope we will have available in the next month.   There were some basic articles written in October, including https://jazz.net/library/article/1112 that are for RSA DM but should apply to Rhapsody DM as well.

Depending on the size and number of models I would probably not recommend a single configuration space for all models in an enterprise.  Ignoring performance implications, my general guidance is to set up configuration spaces along producer/consumer lines and use the Dependencies mechanism to control the flow between the producers and consumers.  

Your intuition regarding potential performance problems (at least with the current version of DM) if the configuration becomes very large is correct though and at least for the short term this needs to be a consideration.
