What about net.isr ?

[Marcos Vinícius Buzo]

Hi all.

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
