Well it would seem that a restart on BFGminer has fixed the problem, but I've never had to do that before...
Hmmm... My big issue with revenue decline comes from the fact we aren't solving any blocks. I haven't done any digging, but some posts have said other pools are slow too...
If the entire network is actually slow that means perhaps the last difficulty adjustment was too aggressive. From what I understand, difficulty (technically) can move up
or down, whatever it takes, with the end goal being that the next 2016 blocks take 2 weeks to mine. Not saying the last difficulty increase was flawed or too aggressive, but if this is a network-wide issue we should expect to see it reflected somehow in the next difficulty calculation.
blocks are being found every 8.4 minutes. that is faster than the every 10 minutes that it is supposed to be. I've been on Slush since May '13. Slush used to be roughly 10% of the world's hashrate. Now, it is less than 5% so it should take longer to find blocks. as your hashrate goes down the Variance goes up. this means that we will see more very long blocks and very short blocks..
