pf_ring对suricata的提升

32CPU + 62G mem

 std. 的 yaml , pps packet per second  250 k左右
打算进一步用pf_ring 改进一下 ，mark一个

看到这个:
With these changes, at 24 cores, Suricata performance increases from 12,871 PPS to 258,912 PPS; an almost 20X improvement

但这个是 Suricata 1.2 version used ，pope used 2.3.1,是std. yaml应该还有提升空间吧？！
