make sure to use the fastest minerd fitting to your cpu.
forexample if you have a modern intel PC CPU ( i7 ) use minerd-corei7-avx.exe
to really get the best out of your CPU.
There should be a readme you can see which one to choose best
Thanks for the advice, I will need to investigate this further.. just wondering .. for this coin, is it worth cpu mining if theres gpu mining available?
