Increasing Render Times

[videep]

Hello Everyone, 

We have been rendering animations using 3ds Max 2010 and Backburner 2008. Something surprisingly which never happened earlier was that in the animations, some machines render the same frames in 2 hours and some machines render the same frames in 6-10 hrs. This difference is way too huge!

Whenever we render out animations, we face the same situation. The rendering starts around 2h per frame and goes to 10h per frame.

We have kept in mind the number of objects in the scene are too much, but are always constant. They never change. The scene is just so static with only the camera animating.

Also all the machines have the same configuration.

Has anyone also encountered such a situation? Hope to get a solution to this soon.

Thanks in advance,
