The SP30 firmware has a bug which stops them currently reporting the correct speed, however SP-tech are aware of this and it is planned to be patched soon. That is why my SP30's may look a little slow (1Th/s)
Wishful thinking. I hope it gets patched tho' .. again, reading the info via CGminer API is nice, but you need to open the API to the local network. Then, if hosted, you have to make sure no one switches your pools from your accounts to theirs with it .. You can read more from SP30 than from the average cgminer rig ::>>
