hi there
can someone explain me how to use the "suggested difficulty" feature ?
bigger is the SD , bigger is the pps reward value ? that's right ?
what's the best SD for a 2-4 gh/s worker ? , in other pools like btc50, 8 is recommended , and on slush pool "2" is guessed as best value
right now all my workers are set to 1? so i'm wondering if i could increase my income if i set the right SD value
thanx
If you increase difficulty your income will not change - variance in your income per block will increase while total will remain the same, but you will use less bandwidth for your connection and also will put less burden on the server.
For 50BTC the time of your share submission is not so important, so 8 is OK there and they will put less load on their server, so will you on your internet connection.
For Slush it is a bit more important when is your share submitted, that's why he suggests much lower difficulty, so with 4GH you will have a share each second at diff 1 and each 2-3 sec with diff 2.
Try using 5 - you should have a share each 5-10 sec which i think is good compromise between bandwidth and not missing on short blocks, but if you are not happy with the variance of per block income, then reduce the diff to 4 or 3 ... i think 2 is too low for 4GH, but if you are closer to 2GH than try that too.
