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.
So just curious at what point would you need to set a higher difficulty? How many Mhash/s are we talkin'? I know what the website suggests according to Mhash/s but is this realistic? What have others experienced?
When you set a value there, it tells the servers "Don't send me anything less than this." The maximum is whatever diff the server decides to send. For example, one of my miners is set for diff 2 -- most shares I get are between 2-1000, but I often get shares as high as 10M to work.
