Why so many stale shares?
I tried all the pools and I always got around 10-15% refused shares using Java Miner.
Are you experiencing the same thing?
What is your Avg Submit RTT? (Find this information while mining.)
Nonces: Attempted: 6 Rejected: 0 Eff: 100.00% Avg Hash/nonce: 2867 Avg Submit RTT: 964ms
10744 ms... I suppose that is very high, right?
Yes, that's why you are getting so many rejects, by the time your submitted nonce reaches the nodes it's already become invalid
But why is that? When mining Monero/ETH shares are submitted in 60-70 ms. Even mining Iridium to Canada pool, I never get refused shares.
More: ping aro.party resolves to 104.25.12.22 and gives 11-14 ms avg 12 ms.
I'm in Europe BTW.
