Prior to ArcGIS Pro each map used for a service mxd was saved separately.  Now that we are able to have multiple maps in one Pro project how many maps can Pro handle without effecting performance?  Are unopened maps in pro idle or do they take up resources?

Thanks.

Maps are not fully loaded until they're viewed. So, an open map view will be loaded but a hidden map view will not be loaded until it is made visible. Maps that are not open are not fully loaded, but some aspects of them are read. We've tested permutations up to thousands of maps and performance varies depending on content and disk speed. I'd say a more realistic scenario being targeted is a dozen or so maps.

At the 2.5 release of ArcGIS Pro, due out next year, improvements to map loading / unloading have been made to have less in memory when a map is closed etc.

Are you looking to create many Enterprise services from 1 Pro project where each service comes from a separate map in Pro?
