I am trying to learn about mining and am using xmr-stak-cpu on Ubuntu 17.10 to mine with an AMD a10 6800k processor. I haven't seen a single time my miner reporting 100H/s but the stats of my miner on the pool say I have been at that rate for some time. How can I reach this hash rate more often?
Also I tried to use iGPU to mine but the xmr stak miner does not identify it, is it a driver problem since ubuntu 17.10 does not have proprietary drivers.
