Neither -f0 or -f2 seemed to do much.  Maybe .5 or 1 m/hash increase.

Was odd, seemed to start a lot higher though.  Normally, I click "Start Mining" and it reads in the 80's-90s for a few secs before hitting around 195-200.  With the -f0 and -f2 it started at 220 but quickly dropped into the 195-200 range.
