请大家不要一味追求速度，一味提高cpu的性能，是否挖到矿，不单由primespersecond决定的。
getmininginfo能知道primespersecond到底是多少，台式机的i5 cpu一般在500以上，笔记本的要弱很多。

下面是primecoin的发布者Sunny King说的：

Please note primespersecond is not an accurate measure of actual performance. It has some correlations but if sieve round is reduced too short you could see inflated pps but not really faster performance. Only block rate is an accurate measure of true performance.


下面是我的笔记本i5 cpu的pps，才有323。
