Mining a primecoin based currency (datacoin). How do I find out how much hash power im doing?
Base on your screen shot, in theory, you are contributing 808 hash per second (primepersec), but this may not realistic, though.

How you get that screen shot? That is the correct command.

If you are using Qt, click on help > debug window > console then enter getmininginfo at the bottom ">" prompt. type help for other command.
