Its a nice firmware with solid features, but don't expect much regarding performance. Latest Bitmain firmware does better regarding Ths/W (or at least mine S9 couldn't do better on this firmware)

@Patrik

I noticed that after reverting back to latest Bitmain firmware the consumption got higher on ELPM. Previously for S9 ELPM was 9.5Ths/760W now i get 9.5Ths/860W (this performance was also on vnish when mimicking ELPM). Can you check with developers of vnish what could possible be the reason for this?
