Hi Doug, I'm attaching the source code where I'm creating 1000 sphere and it takes around 7 secs to render it. If I increase this number to 15000 it takes 100+ secs, however in both the cases initial number of spheres visible on the screen are same.

It sounds like you are hitting a strange case. Do you have an example that you can post.
