will the hash rate be lower on solo pool than other pool such as kano.is?  For Antminer products I get significantly lower hash rate on solopool than kano.is.  It seems that this is the case with newer S3 chip firmware for both S3 and C1.  Is this to be expected due to cgminer or that it is mining solo.  C1 is about 100GH lower and S3 about 40-50 GH lower.
