I have a top level assembly with about 175 routing assemblies (hydraulic hoses with ends) inside. Valves and clamps and frame components are all in the top level.

Those hoses were all modeled as virtual parts.

The assy file is about 142MB, and modifying the hoses is now very slow.  I am trying to modify a copy of them for another installation.

Check-in is often 15  min or more due to all the in-context references.

Does anyone have a best practice for increasing the regen / save / checkin time?  Any structural recommendations?

I'm On SW2014 SP2, with SolidWorks EPDM
