Info would be helpful, i'm dumb when it comes to cpu mining.
Traumschiff, I'm mining on a Phenom II 965 running 4 instance of simpleminer. Averaging ~50h/s on the pools,it will fluctuate depending on the shares submitted. So i guess yours should be more. I'm getting an average of 0.023MRO per block, peanuts but its better than nothing. .
I'm currently pointed to extremepool.org. You can check the pool block info here http://extremepool.org/#pool_blocks. But as of now the last blocks found was 7 hours ago, maybe due to the fact that the net hash is getting higher by the hour.
