Does a Pool’s Software Client (The Miner’s Program) Have Any Features to Mitigate the Effects of High Latency?
Yes, some advanced mining software clients have features to mitigate the effects of high latency. These can include connection failover mechanisms to automatically switch to a lower-latency backup server.
Some clients also employ "ping" checks and local share caching to minimize network communication delays. However, no software can fully overcome extremely high physical latency.
