Motion Study is very slow for Geneva Mechanism

Hi,

I'm building a demo for my students by integrating Geneva mechanism to NI LabVIEW. The problem is the motion analysis is very slow although I have few parts and my Laptop is core i5 with 8 GB of RAM and 1GB ATI Radeon VGA card. I have seen demos from NI with more components but much performant.I tried to remove background and even unified materials for all parts, but still very slow.

I have enclosed the files. Hope someone could correct me about increasing the performance. Thanks to all.
