Hello everyone.
By many experiments were obtained the optimal settings for personal nodes. After fine tuning the node parameter Bitcoind GetBlockTemplate Latency has dropped from 5-10 seconds to 0.1-0.2 seconds. The average DOA decreased from 5-7% to 1-4%. The amount of dead shares fell to zero. For normal operation, S5 and S7, you must use proxy from ckpool.
For use attaching the selected parameters.
