CPU/GPU Iso creation process seems slower

[bigbwb]

I recently build a new Windows 10 PC for streaming and ripping. I utilized some parts from the old pc etc. The new one is has a much faster CPU (i5) and a SSD rather than my old HDD. Anyway, I rip all of my blu rays using main movie, ISO (no compression). I have CUDA selected being I have a NVidia GT430 card.

The first part of the process of ripping the file from the disc to the SSD goes fast but the creation of the ISO image takes 3-4 hrs (seems longer than before). Could it be that I selected my extra HDD as the destination folder for the rips rather than the SSD to preserve it?

Any other thoughts or things to look for?
The actual speed is showing 1.7x (2.25mB/s)

Update:
After reading another thread it seems as if fab v9 might be to blame so I downloaded the last version of 8xxx QT, setup everything identical to my current setup in version 9 and sure enough..... I'm now getting speeds of around 6.5x while the ISO is bring created.

So what gives?? Suggestions?
