DaVinci - slow processing

We buy Resolve, HD extreme 3D card and Quadro 4000 card, but Resolve processing is very slow.

I try this "Candle test": http://forums.creativecow.net/thread/277/20501#20501

V01 04 blur nodes 12 fps
V02 08 blur nodes 7.5 fps
V03 16 blur nodes 4.5fps
V04 32 blur nodes 2.5 fps
V05 64 blur nodes 1.5 fps
V06 01 NR 2 nodes 4.5 fps
V07 03 NR 2 nodes 1.5fps
V08 06 NR 2 nodes 1 fps

My configuration:
Mac Pro (Mid 2010), Mac OS X Lion 10.7.5
Model Identifier: MacPro5,1
Processor : 2 x 2,4 GHz Quad-Core Intel Xeon
Memory 32 GB 1066 MHz DDR3 ECC
Slot 1: ATI Radeon HD 5770 (monitors - GUI)
Slot 2: NVIDIA Quadro 4000 (no monitors, only for processing)
Davinci Resolve: 9.0.1.010

Where is problem? Any suggestions?

These speeds seem correct as you are using the q4000 for processing. It's one of the slower GPUs and is more suited for GUI,
