Wow, my CPU is a lot worse than I thought it would be at this. However, CPUMiner is only using around 30% of my CPU, odd. Is anyone else having this issue? The built-in miner seems to be doing fine, is there any way I can check the hashrate of it?
Be sure to set the value after -T to number of threads on intel, or number of cores on amd. This will utilize all of your processors potential.
