Sounds like Performer is trying to build up a display list for the object
when it comes into the scene. If this is a large object, it will take a
few seconds. Once the display list is created for the object, however, it
doesn't need to be created again (unless geometry or display attributes
change, of course). To resolve this problem it seems like you would want
to build the display list for each object before beginning the simulation.
However, I'm not exactly sure if you can do this or how to do it. A good
place to start looking would be the man pages for pfDispList.
