As I already mentioned: I think the pool is ripping off miners… at least 40% in my case I switched to flypool using ZOGMiner and with roughly the same hashrate I am getting 2x the payout. Whether deliberately done or through incompetence this pool deserves to be abandoned!
The reason why people flock to coinsforall is the good miner, but ZOGMiner has caught up. If you start 2 instances of ZOGMiner per AMD GPU like:
./zcash-miner -G -stratum="stratum+tcp://eu1-zcash.flypool.org:3333" -user=<ZCash_TADDRESS>.<WorkerName> -printtoconsole -S=0
then you achieve roughly the same hashtrate. -S=0 means GPU 0.
