Does scene size affect render times?

[hellobard]

I was wondering, does the size of my scene affect V-Rray's render times?

I've started bumping up the size of my scenes, using the sizes of the Mudbox default human as a reference object (which is about 185cm) and setting Maya to cm's. The default size of V-Ray_Rect_Lights are pretty small at this scene size.

Is it ideal to use this sort of scene size? What is everyone else doing?

The scale doesn't matter that much, so long as it is not way too small or way too large.

Best regards,
