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: http://linux-net.osdl.org/index.php/TODO#TCP and thread http://marc.theaimsgroup.com/?t=116695290600001&r=1&w=2, read from bottom. -- Sincerely, Robert Iakobashvili, coroberti %x40 gmail %x2e com ...................................................................
