I tried that.
It only starts with 2 cores and ridiculous low hashrate (about 10h/s total).
Meanwhile mining solo with the wallet and 8 cores gives 850h/s.
The wallet shows your hashrate in h/m.
850 h/m = 14.17 h/s
I see... But anyway i have at least 4GB free memory, only 2 cores working with the miner?
