In solidworks 2012 sp4 I never had a problem bringing in parts, mating them, or copying parts with mates however in SW13 my assembly builds have become much more slow.

I am assuming that the reason behind this slow build is due to the fact that now every part rebuilds once a new part is mated into position.  Is there a way to turn of the part rebuild so that I can rebuild it after all of the parts are in position?

In the copy with mates tool, it seriously takes me one click, then a solid minute of waiting, then on to the next mate click, etc.

I must mention that the parts that take a long time to mate are both parts that have relations to existing geometries in the mold as well as parts that have been built completely independant of the mold geometry
