Do we need to change also sievePerRound to 7 ?
in my case it automatically adjust SievePerRound:
Work received: height=2555695 diff=10.991005 latency=31ms
* warning: no enough candidates (16071 available, must be more than 16384
increase sieves per round to 13
.
.
Work received: height=2555703 diff=10.99101 latency=46ms

increase sieves per round to 12

You do not have automatic mode for parameter SievePerRound, look carefully at the log that you post
Anyway, the lowering of CPD with more than 28-29 times as mentioned by eXtremal (and this is a real), not means that your income will lowering with 28-29 times
