= SUMMARY =

Unexplained long render time may be a result of instances that your scene contains. In order to render instances, the mental ray renderer must internally tessellate them as if they were real objects. Even if the scene has a low triangle count, at render time this number can increase drastically if there are many instances.

Instances cause slow render performance as well as using up additional memory and swap space. So when you use instances, keep in mind that they are expanded at render-time.
