First things first: Hats off to the developer and all co-developers/ contributors for making SH3D such an amazing piece of software!

I have been trying to fasten the speed at which photo-realistic images are created - here are the details:
SH3D Room size: 110 MB
# of lights in room: 2
CPU: Intel i7 4510U (2 Ghz)
RAM: 4 GB
Have extended SH3D memory utilization to 1GB
Made furniture objects not in the camera viewport invisible

Result: 42 seconds

My Question to this forum is: How much faster can I render photo-realistic images via SH3D, if I were to use better CPU on a server? What server specifications would you recommend?

Thanks in advance folks!
