I just wish I could get my chainspermin up. tried sievepercentage 6 and 12, and tried roundsievepercentage 40... they did not do better than the above.
did you try 100K/10/30?
Here are the settings that yielded the highest CPM w/good to great PPS.
"roundsievepercentage" : 40,
"sievepercentage" : 8,
"sievesize" : 200000,
"roundsievepercentage" : 25,
"sievepercentage" : 10,
"sievesize" : 100000,
"roundsievepercentage" : 20,
"sievepercentage" : 8,
"sievesize" : 100000,
"roundsievepercentage" : 30,
