Riduculously long time to process 1 WU

I think you were crunching the wrong work units. For the challenge anyway.
Set your primegrid preferences to the PPS LLR (proth prime search) workunits in your account menu.
Seems the link provided in the challenge thread, points to the LLR cullen workunits. :0
After the challenge I recommend sieving, with the consideration of your 64 bit O.S. They do tend to pay a bit better.
