why is the diff so high in version 13.1?
9k is a little bit high isn't it?
I don't get any shares. What can I do?
I think it has to do with the new dust payout elimination feature. It raises the difficulty enough to minimize transaction fees when spending mined coins. It appears you may be able to reduce the share difficulty again by adding +n to the miner username, where n is the desired share difficulty. However, you may incur heavy transaction fees in the future when you go to spend the mined coins.
Maybe someone can confirm this for sure. I've been finding it difficult to find detailed p2pool documentation lately for some reason.
3x longer shares = 3x higher difficulty = shares last 3x longer = approx. same payout per share per before, just find them less often and they stick around for longer.
The dust payout feature would raise difficulty on people, but I think that is more evident on LTC than BTC. I think the difficulty of dust in BTC is something like 1.5 or 2, but it is something reasonably larger on LTC (since LTC difficulty is commonly < 1)
