Hello, yesterday i started mining bitcoin with guiminer and i'm not quite sure if im doing it right, because i noticed here: https://de.bitcoin.it/wiki/Mining_hardware

that the m/hash im having is much lower than in the list.
In case i was configure guiminer then fyi all i did was insert my worker name and select the pool, am i suppoused to do anything else in order to get the wanted m/hash rate ?
