Mam dwa routerki oparte o supermicro - identyczne.

Na jednym jest stary debian 6.0 na drugim nowy 10.

Na starym /proc/interrupts:

  27:  541639089  585403534  560324750  525012511   PCI-MSI-edge      eth0-rx-0

  32:  207489178  207500768  207386329  207363676   PCI-MSI-edge      eth1

na nowym:

 27:  107405195          0    6220041  100161479   PCI-MSI 1048576-edge      eth0-rx-0

 30:   84963416          0  113490109          0   PCI-MSI 1572864-edge      eth1-rx-0
 31:          0          0    2352928    3872645   PCI-MSI 1572865-edge      eth1-tx-0

no i nie pracują wszystkie kory/wątki a na starym debianie jak widać pięknie się to rozkłada.

maska IRQ affinity:

root@bgp-ior:~# cat /proc/irq/27/smp_affinity 
f

czyli że wszystkie, ale ruch się nie rozkłada.
co zrobić by jednak firewall (głównie to obciąża) działał jednak (kernel) na wszystkich "procesorach"?
