Something I really dislike about your miner Claymore is the fact that if I'm dual mining ETC, when DevFee starts I lose another 30-40 seconds because it needs to swap to a different DAG and then after DevFee ends it changes again to a different DAG (132 on ETC 130 on ETH).
I really, really dislike it about your miner.
Just set an ETC pool for your devfee if mining ETC for christ sake, I understand you do a good job with your miners (you also make an awful lot of money, but it's cool anyway, it's deserved), but that's a long way from 1-2%, it's much closer to around 5% of lost hashrate each our with this dag swapping.
