Question: Suggested difficulty option box.
What is the point in this box? It optional but then if its optional dose it really matter? I'm running just 4 Block Erupters on Slush's Pool should I change my setting and if so to what?
For those with large amount of hash power, setting a higher difficulty will reduce the network bandwidth consumed by submitted shares. You don't have enough hashpower for it to matter. I wouldn't worry about it.
