so once the dag was made you can benchmark..
so the work around would be to put a high number manually in, like 50000000 then hit start, let it make the dag and stop and it run the benchmark.
Where are you putting this number in ? I see no area in which to enter any numbers....
I let it run 1 hour and still nothing...
EDIT: Almost two hours now.. I'm guessing it's not because I didn't give it enough time to download the DAG....
