How Does the Distance between the Miner and the Pool Server Affect the Stale Share Rate?
Greater distance increases network latency, as the data packets must travel farther, leading to a higher stale share rate. The delay in receiving the new block template and submitting the share increases the chance that the share will arrive after the block has been solved.
Miners should choose a pool server geographically close to their operation.
