Question about entities

[bender]

I've placed this on the ruby forum, but realized this might be a better place?

I am working on an animation through the reading of a log file. As I am reading it, I am placing entities on the space in Sketchup. It starts off quite fast and gets progressively slower, until it is all very very slow. I am placing quite a bit of entities on the space, (100? maybe more). Is this too much? Is there a way around it? When placing the new object (entity), I use the add_instance method. What do you guys think?

Thank you as always. Benderbender
