Hi Mark,

I have a machine with 2 dual core CPUs. This machine runs Fedora Core 6.
I have two Intel e1000 GigaBit network cards on this machine; I use bonding so
that the machine assigns the same IP address to both NICs ;
cat /proc/interrupts shops something like this:
CPU0 CPU1 CPU2 CPU3
50: 3359337 0 0 0 PCI-MSI eth0
58: 49 3396136 0 0 PCI-MSI eth1
CPU0 and CPU1 are of the first CPU as far as I understand ; so
this means as far as I understand that the second CPU (which has CPU3
and CPU4) does not handle
interrupts of the arrived packets; Can I somehow change it so the second
CPU will also handle network interrupts of receiving packets on the nic ?
Can I assign one CPU to eth0 and the second CPU to eth1 ?
How it will help you?
Y can set smp-affinity mask for each irq in /proc/<irq-number>/
google for 'linux smp-affinity".
The subject in more details is discussed in:

and thread
