I have a dual Intel Xeon E5506 box running mpd5, dummynet and pf. Sometimes i get about 500+ pppoe connections to this machine, the network traffic goes to 30mbps and CPU usage hits 100%. I would like to know if netisr would help me using the other processor cores, and where I can get docs about it. My network card is a dual port Broadcom NetXtreme II BCM5709. Thanks in advance
