Long Save Times

We have assemblies with 300 to 500 parts on average in them.SW is taking 10 to 20 minutes to save each time. The assemblies ismade up of 5 parts but some of the part have 100s of configurationsin them. I am pull the parts from a library each time. Is there asetting that needs to be turn on or off to help with the longsaves? Or could it be how the parts and assemblies are beingmanaged?SolidworksAdministration
