There is some useful advice on how to choose a difficulty here:
https://bitcointalk.org/index.php?topic=274023.0It helps to know the default settings for all the worker settings. How am i suppose to adjust them effectively without knowing what the default is? I only have 10erupters running and would like to maximize their potential.
The defaults are:
Minimum difficulty: 1
Work submits per minute: 20
Merged mining flushing of stale work: on
Stratum extranonce2: 6 bytes (may change to 4 in the future, if you run a subpool and need a certain number of bytes, set it explicitly)
